Product Summary

The AD8222ACPZ is a dual-channel, high performance instrumentation amplifier that requires only one external resistor per amplifier to set gains of 1 to 10,000. The AD8222ACPZ is the first dual-instrumentation amplifier in the small 4 mm * 4mm LFCSP. It requires the same board area as a typical single instrumentation amplifier. The smaller package allows a 2× increase in channel density and a lower cost per channel, all with no compromise in performance. The AD8222ACPZ can also be configured as a single-channel, differential output instrumentation amplifier. The applications of the AD8222ACPZ are Multichannel data acquisition for ECG and medical instrumentation, Industrial process controls, Wheatstone bridge sensors, Differential drives for High resolution input ADCs and Remote sensors.
