AD8225: Precision Gain of 5 Instrumentation Amplifier
Product Description
The AD8225 is an instrumentation amplifier with fixed gain of 5 that 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.
