Instrumentation: Get to know op amps; use a curve tracer: For the out of the ordinary application, it is not surprising to find op amp spec sheets wanting

摘要

Describes the application of a transistor curve tracer to measure operational amplifier characteristics, test, circuits and results are shown. Open loop gain, input offset, common mode rejection, power supply rejection, supply rejection, supply current/supply voltage, and noise measurement and curves are described.
