Product Overview

The ADA4638-1ARZ is a High Precision Zero-drift Amplifier features rail-to-rail output swing. It is guaranteed to operate from 4.5 to 30V single supply or ±2.25 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 0.05µV/°C, no 1/f noise and input voltage noise of only 1.2µV p-p (0.1 to 10Hz), the 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 this amplifier to maximize the signal-to-noise ratio (SNR).
