ADI instrumentation amp has 80dB minimum CMR

The AD8225 instrumentation amplifier from Analog Devices Inc. offers a minimum common mode rejection (CMR) of 80dB at frequencies of up to 10kHz, enabling the device to extract and amplify low-level differential signal in the presence of high common-mode voltage levels.

Designed to be used in industrial and medical applications, the 8-lead SOIC device provides a fixed gain of 5 and a 900kHz bandwidth. It has a slew rate of 5V/5s and a maximum gain drift of 5ppm/0C.

The device also has a maximum input offset voltage of 1505V and an input bias current of 1.2nA.

The AD8225 is operates from -400C to 850C and is priced at $2.95 per unit in 1,000-piece quantities.
