Analog Devices ADA4638-1 30V Precision Amplifier

Analog Devices ADA4638-1 30V Auto-Zero, Rail-to-Rail Output Precision Amplifier features rail-to-rail output swing and is guaranteed to operate from 4.5V to 30V single supply or ±2.25V to ±15V dual supplies while consuming less than 0.95mA of supply current at ±5V. With an offset voltage of 4μV, offset drift less than 0.05 μV/°C, no 1/f noise, and input voltage noise of only 1.2μV p-p (0.1Hz to 10Hz), ADI ADA4638-1 is suited for high precision applications where large error sources cannot be tolerated. Pressure sensors, medical equipment, and strain gage 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). ADA4638-1 is specified for the extended industrial (−40°C to +125°C) temperature range.
