Product Summary

The AD621AR is an easy to use, low cost, low power, high accuracy instrumentation amplifier that is ideally suited for a wide range of applications. Its unique combination of high performance, small size and low power, outperforms discrete in amp implementations. High functionality, low gain errors, and lowgain drift errors are achieved by the use of internal gain setting resistors. Fixed gains of 10 and 100 can easily be set via external pin strapping. The AD621AR is fully specified as a total system, therefore, simplifying the design process. For portable or remote applications, where power dissipation, size, and weight are critical, the AD621AR features a very low supply current of 1.3 mA max and is packaged in a compact 8-lead SOIC, 8-lead plastic DIP or 8-lead cerdip. The AD621AR also excels in applications requiring high total accuracy, such as precision data acquisition systems used in weigh scales and transducer interface circuits.
