AD8221ARM-REEL7 GENERAL DESCRIPTION

The AD8221 is a gain programmable, high performanceinstrumentation amplifier that delivers the industry’s highestCMRR over frequency in its class. The CMRR of instrumentationamplifiers on the market today falls off at 200 Hz. In contrast,the AD8221 maintains a minimum CMRR of 80 dB to 10 kHzfor all grades at G = 1. High CMRR over frequency allows theAD8221 to reject wideband interference and line harmonics,greatly simplifying filter requirements. Possible applicationsinclude precision data acquisition, biomedical analysis, andaerospace instrumentation.
