App note from Apex Microtechnology on determining the full bandwidth of high power op amp. Link here (PDF)
Getting the highest bandwidth out of a Power Op Amp is one of the most common challenges in highpower analog. Whether you’re outputting a 3 MHz sinewave into a semiconductor during testing, or getting the sharpest corners on a 100kHz triangular wave to drive a mirror deflector, more bandwidth is always in high demand. This note gives a quick reference for determining the full bandwidth of an Apex product and for maximizing that speed to its full potential.
