The AD623 is an integrated single supply instrumentaTIon amplifierthat delivers rail-to-rail output swing on a single supply(+3 V to +12 V supplies). The AD623 offers superior user flexibilityby allowing single gain set resistor programming, andconforming to the 8-lead industry standard pinout configuraTIon.With no external resistor, the AD623 is configured forunity gain (G = 1) and with an external resistor, the AD623 canbe programmed for gains up to 1,000.The AD623 holds errors to a minimum by providing superior
AC CMRR that increases with increasing gain. Line noise, aswell as line harmonics, will be rejected since the CMRR remainsconstant up to 200 Hz. The AD623 has a wide input。
