In this episode of Electronic Basics I will explain the three golden rules when working with OpAmps and how to use them in order to understand and build all kind of OpAmp circuits. The main focus will be the noninverting and inverting amplifier and the comparator circuit. - Věda a technologie
I watched this video 2 years ago and didn’t have a clue what was going on. I rewatched this video today and understood everything just fine. I don’t have a college education in electrical engineering. I just learn from CZcams and experimenting. Don’t give up!
OpAmp = Overpowered amplifier
Yes same with me, i just study electronic using youtube
Thanks for this comment, I have no idea what's going on. Trying to build a amplifier and I feel like I have a long way to go.
Its gonna take me two years !?
Thankyou for motivating
I know circuits, love your videos, and just watched this for a second time. This is a ridiculous whirlwind of great information but delivered at an absurd rate. Please continue the great work but SLOW DOWN for the basics videos!
Man you seem to know what your doing, just found you not long ago but your so fast in your explaining how things work that i can never fully understand what your trying to say. If these videos are basics for beginners then im sure so many more people would love to watch these videos, cause they are knowledgable and you do cover alot of things people need and love to know. Your great at what u do, so if u could take the time and explain stuff more slow, and thoroughly im sure im not the only one who would love and appreciate what u do even more. Thanks keep doing great work.
For anyone wanting a deeper dive into opamps i can recommend EEVBlogs video on that topic from a few years ago.
What a wonderful oscilloscope! I am an old technician, from the days of vacuum tubes, back in 1960. My "most advanced " scope was an Eico 460 - I enjoy your videos.
I love your videos. I’m an old, rusty, electronics technician (two year bachelors course at An electronics “college” when they still taught basic principles but that was in the eighties) but for me this went so fast. I got about 1/3 of it. I do thank you for showing me very clearly I need to go back to school, go back and read my electronic principles books from school again.
I love your channel!
It never fails. Whenever I want to look something up to either see if it’s the right component for the task, or to learn how it works, you’ve always got great videos that help me progress quickly and very rarely slow down unless I want to dive deeper.
Thank you!!!
Excellent work there. I've used opamps so many times I could probably make an amp while sleeping, now class D and T are so fun to build (love building them!).
Basics you say?
@eman khaled Even after having learnt it before, I don't really understand the contents here, because its hard to imagine the whole circuit. There are lots of stuff going on in an op-map circuit to satisfy the mathematics equation by using electrical components.
Who else enjoys watching GreatScott's videos but barely understands anything? 😂
It's good review at the very least
Very good point
It's difficult to understand his videos because he just slams facts at you but doesn't elaborate. The only way you'd follow this video is if you knew about op-amps before hand, in which case, why would you be here?
🙋🏻♀️🤣🤣
He is splurging too much info too fast. Both audible and visual (formulas) which causes my brain to freeze thoughout the whole video.
Hey your videos are great, in fact your the first place I go to for explanations on components, keep them coming!!
Love your videos, great job using correct terminology!
Great Video as always: I like that you go a bit fast to have all the info in a few minutes. I can go back to the part I need to clarify again. Keep up the good work! :)
this is the first video of great scott where I didn't understand even half of what op amp is. And I'm a final year student of Electrical Engineering Bachelor degree. Wow Im so dumb dude
I subscribed to your channel after watching this video. I finally feel like I understand the basics of Op-Amps. The derivation for the inverting op-amp formula in particular made it click for me. Thanks!
Mr. Chow, my electronics instructor used to say, "DC is the horse and AC is the rider". BTW, I loved the op amps in college and built some cool circuits in the lab. I became intrigued with op amps when I found a book about op amps when I visited an old Heath Kit store in the 70's.
your timing is spot on the other night i was looking into building a 12 channel EQ and that little tid-bit of ICs with 4 OpAmps makes my layout so so much easier back to EasyEDA (thanks for that vid too) I want to build a head unit with only a dock for my nexus that runs on BT. Behind the dock would be 24x 20mm linear slide pots
This video did a great job of explaining why I don't understand op amps....
That was refreshing !!! I grew up with these kiddies in the 70s, still am in love. Now go to JFET opamps and those goodies. THANKS !
Perfectly paced video. Thank you.
This is a great video. I am an electrical engineering student, and this is a simple explanation that helps me out.
I like how your videos are simple and informative, I did my own research on OpAmps quite a lot before but didn't understand what you explained in a couple seconds.
I guess I can start working on my 12AX7/D-class guitar amp again, thank to you
I love this channel,he teach in so much easy way.
Fantastic Video Dude. Really Helpful. It would be good to see some more Videos about Op Amps. Keep up the great work. Nick.
Thank you for the explanation. The hint with the 10 kOhm resistor between "input +" and GND made my day. I don´t exactly understood its neccessarity at this position but it worked (All what matters for now).
some time ago i'll probabbly jump this video in th part of types of opamps... but since i have those lessons on university, i can see what i learned being usefull and have some sense! amazing Scott
this vid is really helpful ,keep continuing this electronic s basics
How serendipitous! I selected this one hoping for discussion of microphone amplification.
I love your videos,They are awesome.My TV has wifi and I stream your videos to take a break or while killing some snacks.Your videos are better than cable.
Very clever explanation. Thanks.
Thanks for this Video, really nice, just like allways. I hope that I can now understand op Amps. I will try tomorrow.
You are GREAT! Greetings from Argentina. :)
Another awesome video scott.
Honestly as someone who knows about op-amps, I suggest you go slower. You rushed through so quickly! I KNOW the concept and found it difficult to catch up to your speed.
Watch it multiple times or pause the video inbetween.
his vids are grea but way to fast.
Nobody would watch if the video lasts 15min...
Just take the bloody criticism and slow down.
+xgenesys
Actually, I would.
I typically listen to his videos, without watching them a few times and then when I am able to spare the time I sit and watch them. That works, but I wouldn't mind a slower video. I watch his other series, and those are paced pretty correctly. But maybe with this series they should be more lengthy episodes.
+GreatScott! Great job, Excellent videos.
I learned from you a lot more than i did in school thank you thank you
Good work as always.
Excellent tutorial series. thumbs up ;)
Loved this one.
3:30 FINALLY someone told me about this
thanks! i have recently received exactly 100 LM358 OP Amps (which only costed $4 lmao), and now i actually know how to use them.
Great Scott you knowledge is great
Excellent, clear! Thanks!
Great Scott you are truly great
I like how Scott is casually using a 14k Oscilloscope. Lol, I hope I can get one some day.
Great videos, kudos to you man, you deserve it.
Great Video very well described!
Very good video!
More electronic basic please!!
Thank you! Great video!!
Thanks a lot man it really helps
I like how he says "let's get started" exactly the same every video! :)
Really great
Yeah finally!
Can you make a video about 555 ? Thanks.
+Parker John oh yeah, the classic and loved by everyone IC555. totally agree
a 555 Video would realy be great!
h made it
Had to stop few times while watching videos to google something, but this video is golden :)
it just clicked thanks to ur vid, thanks a lot !
very good idea I am a loyal fan of your channel .. always successful
Didn't know how they work at start and still no idea after watching it, you are presenting it as if you are explaining it to a professor and not to a beginner.
This video is just awesome
Great video !!!
FINALLY!! OP-AMPSSS!
Nice tutorial!!! Danke!!
yes finally thank you +greatscott for this video :D
Great video bro 👋
Nice Video but WAY TO FAST. I still gave you a thumbs up for all the good information. I felt like I was in speed electronic training. Thanks for sharing. Best Wishes n Blessings. Keith
I agree.. I would like to see this same content, but in about 30 minutes of explanation!
Hello GreatScott, I still watch your videos regularly!! Great work good going!!!
I had another project suggestion in mind - can we use arduino to program an air conditioner or heater, to turn on and turn off automatically, depending on the set max and min room temperature?
Maybe make a switch with a temperature sensor which is programmable like so?
Thus saving electricity!!!
great video. i feel like you can revisit the hand warmer and the cooler idea one more time to do better youre a smart fella
Thanks Scott.
Good video.
I didn't understand a word of this after hooking up the first ground and 12V but your voice is cool anyway. Rock on dude.
I would like to see, as a future project, a very simple audio mixer that can take 5 inputs and feed my speakers from all 5. I do not need level controls or any thing like that as each has its own volume. Cool project! Love them all!
There were Babani Publishing books about this subject. Operational Amplifier User's Handbook ref. BP335 and Circuit Sourcebook 1 ref.BP321 are 2 books that I know in the Babani Publishing series. Others are How to Use OpAmps ref. BP88 and Preamplifier and Filter Circuits ref.BP309.
You are a master!
that was good video, thank you
I like your way of speaking especially the "Let's get started" 😂😂😂
Great video as always, but why the need for a pull down resistor at 1:20 ? Does the non inverting pin have some resemblance with a digital pin on a microcontroller?
Can you please do a project about radar technology. Would love to see that. Great videos you really got me into electronics
Great Video Thank You ,,
This is the first video of the series that skims way too fast over the details of such a large topic. Please make a longer video on opAmps! :)
Honestly I don't have enough time to watch the video but I love your videos so much that I put like , comment then went back to my work
I love you , keep the great work up
+mohamad bilal (Speed King) Thanks mate ;-)
+GreatScott! Welcome
Great tutorial
+GreatScott! Could you please do a video on batteries, c rating, charging, etc? Like for you basics section? And maybe a little discourse on batteries vs ultra-capacitors as far as functionality is concerned?
Sure. I put it on my to do list.
GreatScott! Thank you :D Always excited to see what you've put up! I love this channel
Why did you use that 10K pull-down resistor in the non-inverting amplifier?
In other words, what does it mean to set the reference voltage?
Because the voltage at inverting and non-inverting terminal should be equal.
GreatScott!
great work man , but y go quickly ^^
Most of the people are Technicians. There are very few Engineers like you. Thanks
Ashok. Bangalore
I built an DC - AC power inverter, the control circuit was built mostly with op amps, it was a pain in the arse but it was fun
I have been dealing with general electronics, electro/mechanical repair since the late 70's and have an aptitude for this without any formal training. Like the 555 timer video, this one and others I have watched, you go so fast without explaining that If one does not already know what you are talking about it all flies right over the head.
Example, here are some other comments...
Hani Al Jamal 4 years ago
Who else enjoys watching GreatScott's videos but barely understands anything? 😂
Paul Sampson 1 year ago
It's good review at the very least
Paul is an example of someone who has had training and therefore can understand without explanation.
I really enjoy your electronics videos and I'm experimenting with an opamp, trying to amplify a microphone. I can follow most of whats in this video but there is a part that I'm confused about.
In the first opamp example, you say "A 10k-ohm pulldown resistor to set the reference voltage". I do not understand the reference voltage part and how it is related to using a pulldown resistor.
Keep it up, thanks :)
Please create a playlist of this Electronics basics. 🙏🙏🙏
+Monochrome 680 There is already one
+GreatScott! oh my mistake, i didn't search correctly. Sorry 😉
@@greatscottlab Beginners don't understand what u say. Plz explain tings slower and more Understandable
Hello Great Scott i like your tutorials ! Very simple and productive!
I wanted to ask is there any detailed video about how to use eagle program for pcb layout and how to draw or copy in eagle schematics.
Regards !
That scope you're using, which brand and model is it?
Thanks for a great tutorial, keep up the good work :)
Diagram going to fast
Press pause
Awesome video! Go to the settings icon (looks like a gear) and bump the speed down to 0.5.
slowdown the video
PDF diagrams!
Watch video in 0.5x
+Great Scott! Can you make an extended totorial on split power supplies for op amps?
Hi! Thank for the video. Do you think I could achieve the amplification of a data set of up to 150mV to a step of 0.1mV by following the first circuit and amplifier you used and using 48k and 1k resistors. Are there specifically sensitive test probes you are using for these weak signals?
fascinating!
What do I need to learn to be you? I love electronics but I can't work. I admire you
I have no idea what he's doing
I have no idea what he's talking about
but it's interesting
and as far as I can tell he's doing it very well
..
I think
I would like to say I get it, but I don't get jack shit
+Don Grille Try watching the OP-Amp tutorial from the EEVBlog, more indepth.
+Azagro
Sorry, but eevBlog is pain in the ass, the guy, and the channel..
I would suggest buy a book.
Arsyad Kamili
Pain in the ass? What are you even talking about? The guy has a flawless explanation.
+Azagro I knew you would say that, sorry for any mistone catch of what I'm saying.
Let me tell you, putting 25 minute video almost no cut, just explaining what an op-amps is, no edit, no struggle to make the video looks better, is not how you explain something on CZcams.
He's almost dull, his video is low at "Point per time" score, in another word, 'Very low efficiency".
He's not that type of the guy who plans His video more than 24 hour, look how people explains it in books and another videos, then wrapping it, try to record it again and again until He got maximum result, then make the video great to see. Ask people if they like and understand it, then wait for another few hours to see if His video got any mistakes, then upload it...
In another word, a perfectionist.
Then goes this, His attitude, His obsessing with yellow things, His way of mocking bad products, is really, inapropriate for a teacher to do, coz he's not.
If you want to look at great channels, go to channels like DIY Perks, Collin Cunningham, or Michel van Biezen's video.
DIY Perks is a very good example of how premium channels should look like, He got a very great passion, and sense of beauty for His channel, even though sometimes His project is not very useful to use, He wants His channel looks great, so He buy a very good microphone before He barely got money from His channel.
Michel's video is what you should call " almost flawless explanation". His videos are short, easy to understand, and easy to imagine. Because He's a teacher. Though the video is not really eye appealing, His explanation was beautiful.
GreatScott's channel however, is channel made by a very passionate electronic engineer, He wants people to understand, but there's a language and culture barrier. That what makes His videos too fast, and hard to imagine. You should watch and learn a lot of light stuff before you can actually understand His wideos (Videos).
Collin's video? They're good af, for a total beginner. He's like GreatScott with no barrier but crew, friends, and idea.
Get it now? Anyway every channel has their own cons and pros, and not everybody can make great channel.
+Azagro
Sorry for the long comment..
Took me 40 minute to finish.. :) (See what I did there?)
4:25 Can anyone explain to me what does connecting the plus input to a DC offset achive? And/or what would happen if the plus input was simply connected to ground instead? Thx in advanced.
this electronic basics is a bit quick and advanced for me, i get confused qucikly with the terminology especially if they are so quick in succession without explaination haha, feels like a basic video if you already know what an op amp is
Your explanations are tooooooo......fast!! Didn't get anything from your videos
Nothing at all. Just like having a rapper as a lecturer
called a pause button or just slow down the video
Two solutions. First, slow down the video.
Second, watch the video more than once.
You should listen in a quite place
I'm not good understanding listened english and even sometimes written english, and I'm able to read and follow the subtitles without problem... Also is youtube, you're able to pause and listen again what you need.
