ADA4638-1ACPZ-R7

ADA4638-1 is a high voltage, high precision, zero-drift amplifier featuring rail-to-rail output swing. It is suited for high precision applications where large error sources cannot be tolerated. Pressure sensors, medical equipment, and strain gauge amplifiers benefit greatly from nearly zero drift over the wide operating temperature range. Many applications can take advantage of the rail-to-rail output swing provided by the device to maximize the signal to-noise ratio (SNR). It is used in applications such as electronic weigh scale, pressure and position sensors, strain gauge amplifiers, medical instrumentation, thermocouple amplifiers.
