GENERAL DESCRIPTION

to operate from a single supply, the AD8223 still provides

excellent performance when operated from a dual voltage

supply ( 2 V to 12 V).

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.

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.

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
