The Operational Amplifier (Op-Amp) was developed many years ago for analogue computing. This was in the days when the output information from a calculation was readable with a simple voltmeter.

Selecting the right operational amplifier for a specific application requires you to have your design goals clearly in mind along with a firm understanding of what the published specifications mean.

A circuit model of an operational amplifier is shown in Figure 22. The output voltage of the op amp is linearly proportional to the voltage difference between the input terminals by a factor of...
