Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

Before discussing the various op-amp architectures, it is important to clarify what is meant by the term “precision” op amp. This term typically relates to the input offset voltage of the amplifier.

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. By 1969, a fledgling ...

Who is involved with simulating op-amp design and developing their datasheets? Clarifications on sometimes obtuse amplifier specifications. Pitfalls to avoid when interpreting ac specs. What to watch ...
