## Abstract

The operational amplifier or op-amp is one of the most widely used linear integrated circuits today. Its great popularity arises from its versatility, usefulness, low cost and ease of use. It was introduced in the 1940s mainly for use in analog computers where it performed mathematical operations (hence the name) including addition, multiplication, integration and differentiation. The device later found ready application in a wide range of circuits and functions, many of which will be discussed in this chapter. At the end of the chapter, the student will be able to:
