GENERAL DESCRIPTION
The ADA4638-1 is a high voltage, high precision, zero-drift
amplifier featuring rail-to-rail output swing. It is guaranteed to
operate from 4.5 V to 30 V single supply or ±2.25 V to ±15 V
dual supplies while consuming less than 0.95 mA of supply
current at ±5 V.
With an offset voltage of 4 μV, offset drift less than 0.05 μV/°C,
no 1/f noise, and input voltage noise of only 1.2 μV p-p (0.1 Hz
to 10 Hz), 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
(3 mm × 3 mm) and SOIC packages.
