Practical examples offered throughout this book show how easy it is to design op-amps into a wide variety of circuits. Manufacturers' data sheets are referred to and standard value components are selected. Beginning with a description of the basic operational amplifier circuit, voltage followers, inverting amplifiers and noninverting amplifiers are discussed. Op-amp characteristics and parameters are investigated and frequency compensation methods are thoroughly explored. All of the most important op-amp circuit applications are explained, analyzed, and designed.
