The AD8223 is an integrated single-supply instrumentation to operate from a single supply, the AD8223 still provides amplifier that delivers rail-to-rail output swing on a single excellent performance when operated from a dual voltage supply (3 V to 24 V). The AD8223 conforms to the 8-lead supply (±2 V to ±12 V). industry standard pinout configuration. Low power consumption (1.5 mW at 3 V), wide supply voltage The AD8223 is simple to use: one resistor sets the gain. With no range, and rail-to-rail output swing make the AD8223 ideal for external resistor, the AD8223 is configured for G = 5. With an battery-powered applications. The rail-to-rail output stage external resistor, the AD8223 can be programmed for gains up maximizes the dynamic range when operating from low supply to 1000. voltages. The AD8223 replaces discrete instrumentation amplifier designs and offers superior linearity, temperature The AD8223 has a wide input common-mode range and can stability, and reliability in a minimum of space. amplify signals that have a 150 mV common-mode voltage below ground. Although the design of the AD8223 is optimized
