AD623 is a single-supply, rail-to-rail, low-cost instrumentation amplifier. It is easy to use and offers higher performance than discrete designs. It can operate on single or dual supplies and provides rail-to-rail output swing. The input voltage range extends 150 mV below ground for single supply operation. It has low power consumption with a maximum supply current of 550 μA. The gain can be set with one external resistor and the gain range is from 1 (no resistor) to 1000. It offers high accuracy DC performance with a gain accuracy of 0.10% (G = 1) and 0.35% (G > 1), and a maximum gain drift of 10 ppm (G = 1). The input offset voltage is maximum 200 μV (AD623A) with a maximum input offset drift of 2 μV/°C (AD623A). For AD623B, the maximum input offset voltage is 100 μV with a maximum input offset drift of 1 μV/°C. The maximum input bias current is 25 nA. The noise is 35 nV/√Hz RTI noise @ 1 kHz (G = 1). It also provides excellent AC performance with a minimum CMRR of 90 dB (G = 10) and 70 dB (G = 1) at 60 Hz.
