GENERAL DESCRIPTION AD8223ARMZ

The AD8223 is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing on a single supply (3 V to 24 V). The AD8223 conforms to the 8-lead industry standard pinout configuration.

The AD8223 is simple to use: one resistor sets the gain. With no external resistor, the AD8223 is configured for G = 5. With an external resistor, the AD8223 can be programmed for gains up to 1000.

The AD8223 has a wide input common-mode range and can  amplify signals that have a 150 mV common-mode voltage  below ground. Although the design of the AD8223 is optimized  to operate from a single supply, the AD8223 still provides  excellent performance when operated from a dual voltage  supply (±2 V to ±12 V).
