I'm selecting an op amp for a high-precision signal path and need to choose the best gain-bandwidth product. Isn't faster always better?
Determining which op amp has the right gain-bandwidth product for our application is like Goldilocks choosing which bowl of porridge to eat. We want to choose one that is not too fast and not too slow but gives us just the right trade-offs between speed, accuracy, and stability.
For a closer look at these considerations, see "Choosing a Precision Op Amp? Trust Goldilocks" in the August 2016 issue of Analog Dialogue.
