Product Summary
The AD620AR is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620AR features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making it a good fit for battery-powered, portable (or remote) applications. The applications of the AD620AR are Weigh scales, ECG and medical instrumentation, Transducer interface, Data acquisition systems, Industrial process controls, Battery-powered and portable equipment. The low noise, low input bias current, and low power of the AD620AR make it well suited for medical applications, such as ECG and noninvasive blood pressure monitors.
