Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included.

In part 1 of this series, “ Circuits test key op amp parameters,” we addressed some of the basic op amp (operational amplifier) tests such as V OS (offset voltage), CMRR (common-mode rejection ratio), ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can d… ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally,… ...

In part 1 of this series, we introduced you to three op-amp test circuits: A self-test circuit, a two-op-amp loop, and a three-op-amp loop. The circuits let you test V OS (offset voltage), CMRR ...
