AD8222 is a precision dual-channel instrumentation amplifier that provides a 4mm×4mm package with low noise, high accuracy DC performance and excellent AC performance.
The AD8222 is a dual-channel, high performance instrumentation amplifier that requires only one external resistor per amplifier to set gains of 1 to 10,000. It is available in a small 4 mm × 4 mm LFCSP package, allowing for increased channel density and lower cost per channel without compromising performance. The device can be configured as a single-channel, differential output instrumentation amplifier to provide high noise immunity for remote sensors or to drive differential input ADCs.
