AD8223

Single-Supply, Low Cost Instrumentation Amplifier
Manufactured by:

Product Details

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 and 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.
