ADA4638-1ARZ

ADA4638-1 is a high voltage, high precision, zero-drift amplifier featuring rail-to-rail output swing. The ADA4638-1 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 ADA4638-1 to maximize the signal to-noise ratio (SNR). Typical application includes electronic weigh scale, pressure and position sensors, strain gauge amplifiers, medical instrumentation and thermocouple amplifiers.
