AD623ARZ

Product Summary

The AD623ARZ is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing on a 3 V to 12 V supply. The AD623ARZ 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 AD623ARZ is configured for unity gain (G = 1), and with an external resistor, the AD623ARZ can be programmed for gains up to 1000. The AD623ARZ 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 AD623ARZ 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 AD623ARZ was optimized to operate from a single supply, the AD623ARZ still provides superior performance when operated from a dual voltage supply (±2.5 V to ±6.0 V).
