Analog Devices is introducing a free "hands-on" applications guide, A Designers Guide to Instrumentation Amplifiers - Second Edition, authored by senior design engineers Lewis Counts, design fellow and vice president of the Linear Products group and Charles Kitchin, hardware applications engineer.

Instrumentation amplifiers (in-amps) amplify weak signals in the presence of strong interference and noise. They are commonly used in data acquisition, medical instrumentation, audio, high-speed signal conditioning, video and automotive applications.Therefore, this in-amp guide helps engineers navigate the various options by covering:

In-amp design basics

Selecting between an in-amp and a difference amplifier

Alternating current (AC) input coupling

Input protection basics

Reducing radio frequency interference (RFI) rectification errors

In-amp and difference amplifier applications circuits

Matching in-amp circuits to analog-to-digital converters

Understanding in-amp data sheet specifications
