Op Amp Applications Handbook

"Op Amp Applications Handbook, edited by Walt Jung (Newnes, 2006), comprises Op Amp Basics, Specialty Amplifiers, Using Op Amps with Data Converters, Sensor Signal Conditioning, Analog Filters, Signal Amplifiers, Hardware and Housekeeping Techniques, and Op Amp History. As the name implies, it covers the application of op amps, but does so on a broader scope. It also covers a host of closely related design topics, making it a formidable toolkit for the analog designer."
