GENERAL DESCRIPTION
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 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.
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 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.
For a single-channel version, see the AD8221.
