General Description

The AD8221 is a gain programmable, high performance instrumentation amplifier that delivers the industry’s highest CMRR over frequency in its class.

The CMRR of instrumentation amplifiers on the market today falls off at 200 Hz.

In contrast, the AD8221 maintains a minimum CMRR of 80 dB to 10 kHz for all grades at G = 1.

Key Features
