News New Design Guide for Instrumentation Amplifiers A Designers Guide to Instrumentation Amplifiers is an ideal textbook source for learning about Instrumentation Amplifiers, 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. Between them they have more than 60 years combined experience designing and managing the development of analog integrated circuits. The greatly expanded second edition of the amplifier guide contains tables, graphs and data presented in an easy-to-understand “cookbook” format. It also provides the latest information about Analog Devices’ amplifier products, including difference amplifiers. 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. With a large number of products to choose from, correctly identifying and matching the best in-amp for a particular application can be challenging. 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 Extensive information on the latest Analog Devices amplifier products, including the AD8221 gain programmable, high performance in-amp that delivers the industry’s highest common mode rejection (CMRR) over frequency The company's Web site address is http://www.analog.com/.
