AD623ARZ

The AD623ARZ is a Single-supply Rail-to-rail Instrumentation Amplifier that delivers rail-to-rail output swing on a 3 to 12V supply. The AD623 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, it is configured for unity gain (G = 1) and with an external resistor, it can be programmed for gains up to 1000. The AD623 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 200Hz. The amplifier has a wide input common mode range and can amplify signals that have a common mode voltage 150mV below ground. Although the design of AD623 was optimized to operate from a single supply, it still provides superior performance when operated from a dual voltage supply (±2.5 to ±6.0V).
