The AD8223 offers superior user flexibility by allowing single-gain set resistor program- ming, and conforming to the 8-lead industry standard pinout configuration. With no external resistor, the AD8223 is configured for G = 5 and with an external resistor, the AD8223 can be programmed for gains up to 1000. The AD8223 holds errors to a minimum by providing superior ac CMRR that increases with increasing gain. Line noise, as well as line harmonics, is rejected because the CMRR remains constant up to 200 Hz. The AD8223 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 AD8223 is optimized to operate from a single supply, the AD8223 still provides superior performance when operated from a dual voltage supply (±2.5 V to ±12.5 V). Low power consumption (1.5 mW at 3 V), wide supply voltage range, and rail-to-rail output swing make the AD8223 ideal for battery-powered applications. The rail-to-rail output stage maximizes the dynamic range when operating from low supply voltages. The AD8223 replaces discrete instrumentation amplifier designs and offers superior linearity, temperature stability and reliability in a minimum of space. |
