Abstract

Operational amplifiers (op amps) provide output dc voltages that are related to the input dc voltages by an amplification factor. In combination with other electronic components they serve other purposes also, a few of which will be explained in this chapter. Measurement and control circuits use op amps widely, and the device is a building block of many circuits. The symbol of the op amp is shown in Fig. 3-1 with the inputs on the left and output on the right. Supply voltages of +12 and −12 V are shown leading to the op amp. Supply voltages are always required, and even though the symbol for the op amp may not show the supply voltages, it is assumed that they exist.
