In the intervening years since the first edition was published, there have been many developments in the field of op amps and related design aids. This edition augments the original material in light of these developments, and highlights the new exciting design tools and techniques.

Op amps have increased dramatically in speed, enabling design into the RF domain. New generations of op amps have included fully differential models, which not only return to the op amp's roots, but open up new applications in the interfacing of differential signal chains. Op amp design tools now include not only new generations of filter design and simulation software, but gain and offset design software as well—making the task of the signal chain designer almost trivial. Focus can now be on the selection of the best amplifier for the job, instead of being mired in transfer equations and confusing topologies to interface one signal level and offset to another. It is hoped that a theoretically minded engineer will find this book a useful design reference, but the focus is more on the signal chain designer on a tight schedule, who needs good working solutions to a project with a minimum of calculation. This book includes extensive “how-to” design sections, which will produce very good design solutions rapidly, using readily available components.

I wish to thank John Bishop and Thomas Kugelstadt, who contributed to this edition. A very special thanks to my friend and mentor Ron Mancini, whose material still makes up a very significant portion of this volume. Without his inspiration, there never would have been a first edition of Op Amps for Everyone, let alone a second and third.
