Description

The AD620ANZ is an instrumentation amplifier designed for precision data acquisition systems. It is a low cost and high accuracy amplifier that can set gains from 1 to 10,000 with just one external resistor. This amplifier is available in 8-lead SOIC and DIP packaging, making it smaller than conventional designs and requires lower power consumption (only 1.3 mA max supply current), making it ideal for portable and remote applications. The AD620ANZ has outstanding dc and ac specifications that make it an excellent choice for various applications, such as ECG and medical instrumentation, weigh scales, transducer interface, data acquisition systems, industrial process controls, battery-powered, and portable equipment.
