The AD8222 is the first dual-instrumentation amplifier in the small 4 mm x 4mm LFCSP. It requires the same board area as a typical single instrumentation amplifier. The smaller package allows a 2x increase in channel density and a lower cost per channel, all with no compromise in performance. The AD8222 can also be configured as a single-channel, differential output instrumentation amplifier. Differential outputs provide high noise immunity, which can be useful when the output signal must travel through a noisy environment, such as with remote sensors. The configuration can also be used to drive differential input ADCs.
