Op Amp Applications Handbook www. All rights reserved. No part of this publication may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, electronic, mechanical, photocopying, recording, or otherwise, without the prior written permission of the publisher. Operational amplifiers—Handbooks, manuals, etc. O For information on all Newnes publications visit our Web site at www. ADI , along with those of its worthy competitors, have always had broad applications, but in a special way: they tend to be used in critical roles making pos- sible—and at the same time limiting—the excellence in performance of the device, instrument, apparatus, or system using them.

Think about the op amp—how it can play a salient role in amplifying an ultrasound wave from deep within a human body, or measure and help reduce the error of a feedback system; the data converter—and its critical position in translating rapidly and accurately between the world of tangible physics and the world of abstract digits; the digital signal processor—manipulating the transformed digital data to extract informa- tion, provide answers, and make crucial instant-by-instant decisions in control systems; transducers, such as the life-saving MEMS accelerometers and gyroscopes; and even control chips, such as the one that empowers the humble thermometric junction placed deep in the heart of a high-performance—but very vulnerable—microcomputer chip.

From its founding two human generations ago, in , ADI has been committed to a leadership role in designing and manufacturing products that meet the needs of the existing market, anticipate the near-term needs of present and future users, and envision the needs of users yet unknown—and perhaps unborn—who will create the markets of the future.

The physical product is a highly technological product that, above all, requires knowledge of its possibili- ties, limitations and subtleties. But when the earliest generations—and to some extent later generations—of such a product appear in the marketplace, there exist few if any school courses that have produced gradu- ates proficient in its use. There are few knowledgeable designers who can foresee its possibilities.

So we have the huge task of creating awareness; teaching about principles, performance measures, and existing applications; and providing ideas to stimulate the imagination of those creative users who will provide our next round of challenges. This problem is met by deploying people and publications. The people are Applications Engineers, who can deal with user questions arriving via phone, fax, and e-mail—as well as working with users in the field to solve particular problems.

These experts also spread the word by giving seminars to small and large groups for purposes from inspiring the creative user to imbuing the system, design, and components engineer with the nuts-and-bolts of practice. In some senses, it can be considered a descendant of two early publications.

The first is a set of Op Amp www. Although useful earlier books had been published by Burr-Brown, and by Dan Sheingold at Philbrick, these two timely publications were seminal in the early days of the silicon era, advocating the un- derstanding and use of IC op amps to a market in the process of growing explosively.

Finally, and perhaps more important to current students of the op amp art, would be the countless contributions of ADI design and applications engineers, amassed over the years and so highly evident within this new book. Operational amplifiers have been marketed since , and practical IC op amps have been available since the late s. 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 s has ample application data on which to draw. In this case, however, Analog Devices, Inc. This book brings some new perspectives to op amp applications. It adds insight into op amp origins and historical developments not available elsewhere.

Within its major chapters it also offers fundamental discussions of basic op amp operation; the roles of various device types including both op amps and other specialty amplifiers, such as instrumentation amplifiers ; the procedures for optimal interfacing to other system components such as ADCs and DACs, signal conditioning and filtering in data processing systems, and a wide variety of signal amplifiers.

The book concludes with practical discussions of various hardware issues, such as passive component selection, printed circuit design, modeling and breadboarding, etc. In short, while this book does indeed cover op amp applications, it also covers a host of closely related design topics, making it a formidable toolkit for the analog designer.

The book is divided into 8 major chapters, and occupies nearly pages, including index. This chapter provides fundamental op amp operating information. An introductory section addresses their ideal and non-ideal characteristics along with basic feedback theory.

The two final sections of this chapter deal with the operating characteristics of precision and high-speed op amp types. This chapter, itself a book-within-a-book, oc- cupies about pages.

This chapter provides information on those commonly used amplifier types that use op amp-like principles, but aren't op amps themselves—instead they are specialty amplifiers. The first section covers the design and application of differential input, single-ended output amplifiers, known as instrumentation amplifiers. The second section is on programmable gain amplifiers, which are op amp or instrumentation amplifier stages, designed to be dynamically addressable for gain. The final section of the chapter is on isolation amplifiers, which provide galvanic isolation between sections of a system.

This chapter occupies about 52 pages. The first section is an introductory one, introducing converter terms and the concept of minimizing conversion degradation within the design of an op amp interface. The second section cov- ers ADC and DAC specifications, including such critically important concepts as linearity, monotonicity, www.

The third section covers driving ADC inputs in both single-ended and differential signal modes, op amp stability and settling time issues, level shifting, etc.

This section also includes a discussion of dedicated differential driver amplifier ICs, as well as op amp-based ADC drivers. The fourth section is concerned with driving converter reference inputs, and optimal use of sources.

The fifth and final section covers DAC output buffer amplifiers, using both standard op amp circuits as well as differential driver ICs. This chapter occupies about 54 pages.

After an introductory section on sensor types and their processing requirements, the remaining four sections deal with the different sensor types. The second section is on bridge circuits, covering the considerations in optimizing performance with respect to bridge drive mode, output mode, and impedance. The third section covers strain, force, pressure, and flow measurements, along with examples of high performance circuits with representative transducers.

The fourth section, on high im- pedance sensors, covers a multitude of measurement types. Among these are photodiode amplifiers, charge amplifiers, and pH amplifiers. The fifth section of the chapter covers temperature sensors of various types, such as thermocouples, RTDs, thermistor and semiconductor-based transducers.

This chapter occupies about 82 pages. Chapter 5, Analog Filters, has eight sections authored by Hank Zumbahlen. This chapter could be consid- ered a stand-alone treatise on how to implement modern analog filters. The eight sections, starting with an introduction, include transfer functions, time domain response, standard responses, frequency transfor- mations, filter realizations, practical problems, and design examples.

This chapter is more mathematical than any other within the book, with many response tables as design aids. One key highlight is the design example section, where an online filter-builder design tool is described in active filter implementation examples using Sallen-Key, multiple feedback, state variable, and frequency dependent negative resistance filter types.

This chapter, another book-within-a-book, occupies about pages. In the audio, video, and communications amplifier sections, various op amp circuit examples are shown, with emphasis in these sections on performance to high specifications— audio, video, or communications, as the case may be.

In this chapter, the development of a point-of-care device for bio-medical applications has been discussed. Our main objective is to research new electronic solutions for the detection, quantification, and monitoring of important biological agents in medical environments. The proposed systems and technologies rely on label-free disposable sensors, with portable electronics for user-friendly, low-cost solutions for medical disease diagnosis, monitoring, and treatment. In this chapter, we will focus on a specific point-of-care device for cellular analysis, applied to the case of anemia detection and monitoring.

This book presents innovative solutions in the design of precision instrumentation amplifier and read-out ICs, which can be used to boost millivolt-level signals transmitted by modern sensors, to levels compatible with the input ranges of typical Analog-to-Digital Converters ADCs. The discussion includes the theory, design and realization of interface electronics for bridge transducers and thermocouples. It describes the use of power efficient techniques to mitigate low frequency errors, resulting in interface electronics with high accuracy, low noise and low drift. Since this book is mainly about techniques for eliminating low frequency errors, it describes the nature of these errors and the associated dynamic offset cancellation techniques used to mitigate them.
