GENERAL DESCRIPTION  
The AD8222 maintains a minimum CMRR of 80 dB to 4 kHz  
for all grades at G = 1. High CMRR over frequency allows the  
AD8222 to reject wideband interference and line harmonics,  
greatly simplifying filter requirements. The AD8222 also has a  
typical CMRR drift over temperature of just 0.07 μV/V/°C at G = 1.  
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.  
The AD8222 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 AD8222 operates on both single and dual supplies and only  
requires 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.  
The AD8222 can also be configured as a single-channel, differen-  
tial 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.  
For a single-channel version, see the AD8221.
