Introduction

AI Translation

The ADA4638-1 is a high voltage, high precision, zero-drift amplifier featuring rail-to-rail output swing. It 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 0.05μV/°C, no 1/f noise, and input voltage noise of only 1.2μV p-p (0.1Hz 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 the ADA4638-1 to maximize the signal-to-noise ratio (SNR). The ADA4638-1 is specified for the extended industrial (-40°C to +125°C) temperature range and is available in 8-lead LFCSP 3mm×3mm and SOIC packages.
