Basic IC Op-Amp Design

Most of the basic design information for a particular IC op-amp can be obtained from the data sheet. Likewise, a typical data sheet describes a few specific applications for the op-amp. However, op-amp data sheets often have a weak point. The data sheet does not show how the listed parameters relate to design problems. To further complicate the situation, each manufacturer has a separate system of data sheets. It is impractical to discuss all data sheets here. Instead, we discuss typical information found on op-amp data sheets and see how this information affects simplified design.

3.1 The Basic IC Op-Amp

As discussed in Chapter 1 and shown in Fig. 1-28, IC op-amps generally use several differential stages in ...
