The operational amplifier (“op amp”) is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp.

Op amps for everyone: design reference By Ron Mancini

“The op amp is treated as a completed component in this book.The op amp will continue to be a vital component of analog design because it is such a fundamental component. Each generation of electronics equipment integrates more functions on silicon and takes more of the analog circuitry inside the IC.

Op amps for everyone

Don’t fear, as digital applications increase, analog applications also increase because the predominant supply of data and interface applications are in the real world, and the real world is an analog world. Thus, each new generation of electronics equipment creates requirements for new analog circuits; hence, new generations of op amps are required to fulfill these requirements. Analog design, and op amp design, is a fundamental skill that will be required far into the future.”

Walt Jung – OpAmp Applications Handbook

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.

Walt Jung – OpAmp Applications Handbook

In the past several years, many advances have been made in operational amplifiers and the latest op amps have powerful new features, making them more suitable for use in many products requiring weak signal amplification, such as medical devices, communications technology, optical networks, and sensor interfacing.

Walt Jung, analog design guru and author of the classic IC OP-Amp Cookbook (which has gone into three editions since 1974), has now written what may well be the ultimate op amp reference book.

As Jung says, “This book is a compendium of everything that can currently be done with op amps.” This book is brimming with up-to-date application circuits, handy design tips, historical perspectives, and in-depth coverage of the latest techniques to simplify op amp circuit designs and improve their performance.

This is a like a Opamp Design Quick Reference. All the generic configurations and also example designs help you start building the Analog Blocks for your Instrument, Equipment or Gadget. It would be ideal if you test out all the configurations on a breadboard. Then try building a Measurement device with demanding specs. A Micro-ohmmeter is a suggestion i would give for testing your skills.

Contact resistance of connectors is in micro-ohms. Here contact resistance can also be affected by contamination, thermoelectric EMF. One Amp of current is passed thru the specimen, a connector and the voltage measured. The measured voltage is in micro-volts, a small analog challenge. Sometimes the test current can be even 10 Amps pulsed and the voltage measured quickly. A sample and hold synced with the pulse has to be designed. The voltage sample is taken in the middle of the pulse. Build such things, that will build the analog skills. Remember the Real world is Analog.
