GENERAL DESCRIPTION
The AD8225 is an instrumentation amplifier with a fixed gain of 5, which sets new standards of performance. The superior CMRR of the AD8225 enables rejection of high frequency common-mode voltage (80 dB Min @ 10 kHz). As a result, higher ambient levels of noise from utility lines, industrial equipment, and other radiating sources are rejected. Extended CMV range enables the AD8225 to extract low level differential signals in the presence of high common-mode dc voltage levels even at low supply voltages.
