Op Amp Applications Handbook is another book on the operational amplifi er, or op amp. As the name implies, it covers the application of op amps, but does so on a broader scope. Thus it would be incorrect to assume that this book is simply a large collection of app notes on various devices, as it is far more than that. Any IC manufacturer in existence since the 1960s has ample application data on which to draw. In this case, however, Analog Devices, Inc. has had the benefi t of applications material with a history that goes back beyond early IC developments to the preceding.
