Linear Integrated Circuits As Sensor Amplifiers

"In this fifth edition, we not only have kept the standard 741 op amp but also have shown many circuits with newer, readily available op amps because these have largely overcome the dc and ac limitations of the older types. We preserved or objective of simplifying the process of learning about applications involving signal conditioning, signal generation, filters, instrumentation, and control circuits. But we have oriented this fifth edition to reflect the evolution of analog circuits into those applications whose purpose is to condition signals from transducers or other sources into form suitable for presentation to a microcontroller or computer. In addition, we have added examples of circuit simulation using PSpice throughout this edition."--Introduction.

Now in its third edition, Operational Amplifiers & Linear Integrated Circuits offers an extensive and detailed exploration of the modern op amp and associated specialized linear integrated circuits. The exploration begins with a fundamental building building block, the differential amplifier. The decibel, Bode plots and negative feedback concepts are introduced. The theory of basic amplifier circuits is presented along with applications. Practical performance aspects such as frequency response, slew rate, offset, drift and noise are presented. Chapters are dedicated to specialized devices and applications such linear and switching regulator, non-linear amplifiers, oscillators and function generators, active filters, and AD and DA conversion. Circuit simulations are integrated throughout the chapters. Each of the twelve chapters includes a list of learning outcomes, a summary, review questions and a large number of exercises grouped in terms of Analysis, Design, Challenge and Computer Simulation. Appendices include the answers to the odd-numbered exercises. This is the print version of the on-line OER.
