Instrumentation Amplifiers: Common Application Problems and Solutions-EEWORLD Training

Profile

An instrumentation amplifier is a high-gain, DC-coupled amplifier with differential input, single-ended output, high input impedance and high common-mode rejection ratio, as well as low drift and low noise. Instrumentation amplifiers are compact devices commonly used to amplify weak signals that are submerged in strong interference and noise environments. Instrumentation amplifiers are not only common in instrumentation applications, but are also used in a wide variety of other systems from computers to automobiles. This seminar will focus on the basic principles, circuit structure and key technical specifications of instrumentation amplifiers, and focus on typical applications and solutions to common problems engineers apply when applying instrumentation amplifiers (including single-supply applications). In addition, ADI's representative instrumentation amplifiers will be briefly introduced.
