The AD8222 is a dual-channel, high performance instrumentationamplifier that requires only one external resistor per amplifierto set gains of 1 to 10,000.The AD8222 is the first dual-instrumentation amplifier in thesmall 4 mm × 4mm LFCSP. It requires the same board area as atypical single instrumentation amplifier. The smaller packageallows a 2× increase in channel density and a lower cost perchannel, all with no compromise in performance.The AD8222 can also be configured as a single-channel, differentialoutput instrumentation amplifier. Differential outputs providehigh noise immunity, which can be useful when the outputsignal must travel through a noisy environment, such as withremote sensors. The configuration can also be used to drivedifferential input analog-to-digital converters (ADCs). TheAD8222 maintains a minimum CMRR of 80 dB to 4 kHz for allgrades at G = 1. High CMRR over frequency allows the AD8222to reject wideband interference and line harmonics, greatlysimplifying filter requirements. The AD8222 also has a typicalCMRR drift over temperature of just 0.07 µV/V/°C at G = 1.The AD8222 operates on both single and dual supplies and onlyrequires 2.2 mA maximum supply current for both amplifiers.It is specified over the industrial temperature range of −40°C to+85°C and is fully RoHS compliant.For a single-channel version, see the AD8221.
