Product Summary

The AD622AN is a low cost, moderately accurate instrumentation amplifier that requires only one external resistor to set any gain between 2 and 1,000. Or for a gain of 1, no external resistor is required. The AD622AN is a complete difference or subtracter amplifier “system” while providing superior linearity and commonmode rejection by incorporating precision laser trimmed resistors. The AD622AN replaces low cost, discrete, two or three op amp instrumentation amplifier designs and offers good commonmode rejection, superior linearity, temperature stability, reliability, and board area consumption. The applications of the AD622AN include Transducer Interface, Low Cost Thermocouple Amplifier, Industrial Process Controls, Difference Amplifier, Low Cost Data Acquisition.
