The AD623 offers superior user flex- ibility by allowing single gain set resistor programming, and conforming to the 8-lead industry standard pinout configura- tion. With no external resistor, the AD623 is configured for unity gain (G = 1) and with an external resistor, the AD623 can be 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, as well as line harmonics, will be rejected since the CMRR re- mains constant up to 200 Hz. The AD623 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 AD623 has been optimized to operate from a single supply, the AD623 still provides superior performance when operated from a dual voltage supply ( ±2.5 V to ±6.0 V). Low power consumption (1.5 mW at 3 V), wide supply voltage range, and rail-to-rail output swing make the AD623 ideal for battery powered applications. The rail-to-rail output stage maxi- mizes the dynamic range when operating from low supply volt- ages. The AD623 replaces discrete instrumentation amplifier designs and offers superior linearity, temperature stability and reliability in a minimum of space. Until the AD623, this level of instrumentation amplifier performance has not been achieved. |
