Product Summary

The AD623AR is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing on a 3 V to 12 V supply. The AD623AR offers superior user flexibility by allowing single gain set resistor programming and by conforming to the 8-lead industry standard pinout configuration. With no external resistor, the AD623AR is configured for unity gain (G = 1), and with an external resistor, the AD623AR can be programmed for gains up to 1000. The AD623AR holds errors to a minimum by providing superior ac CMRR that increases with increasing gain. Line noise, as well as line harmonics, are rejected because the CMRR remains constant up to 200 Hz. The AD623AR has a wide input common-mode range and can amplify signals that have a common-mode voltage 150 mV below ground. Although the design of the AD623AR was optimized to operate from a single supply, the AD623AR still provides superior performance when operated from a dual voltage supply (±2.5 V to ±6.0 V).
