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.

Operational amplifiers or op amps are becoming a crucial building block in high-accuracy and high-bandwidth sensor interfaces by providing precision signal conditioning without calibration, thus ...

It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

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 ...

With over 35 years of refinement, op amps are a staple of analog designers. Have we reached the limit of what can be done with monolithic op amps? For many applications, IC op amps are clearly the ...
