GENERAL DESCRIPTION
The AD8223 is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing on a single supply (+3.0 V to +25 V supplies). The AD8223 offers superior user flexibility by allowing single-gain set resistor programming, 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.
