GENERAL DESCRIPTION
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).
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.
