Book excerpt: A guide to the design and application of op-amp and other linear integrated circuits (ICs). Emphasizing fundamental design concepts, it covers the widely used op-amp IC 741 and other linear ICs such as 555 (timer), 565 (phase locked loop), regulated power supply IC chips, switched mode power supply, active filters, D/A and A/D converters. Also discusses IC fabrication technology. Each chapter contains examples and end-of-chapter laboratory experiments demonstrate the use and operation of the ICs described, IC number, pin configuration, and more. Data sheets for important ICs are also included.
