Differential Amplifier Design (Amplifiers #6)

Let's design a differential amplifier with an op-amp that rejects the common mode. This prepares us for the next video where we will make an instrumentation amplifier.

Thank you for making these! I've had some trouble understanding differential amplifiers for a while, but this clears things up! Keep up the good work.

Very helpful for review before my exam. Thank you.

Meaningful details analysis and systematic approach. Thanks.

Or leave the gain = 1 and and another stage immediately after to provide the gain required. This way you get a nice clean signal and at the gain you need.

You beat me to it! He does show a better approach in the next video, but I think it would be interesting to compare your approach with the instrumentation amplifier.
