Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

Today, three test-circuit topologies are commonly used for bench and production testing of DC parameters in operational amplifiers. These three topologies are 1) the two-operational-amplifier test ...

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 ...

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), ...

To allow the comparison of different op-amps in a headphone amplifier, [Stephan Martin] has created a stereo amplifier board complete with sockets to take single or dual op-amp chips.

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,… ...
