GENERAL DESCRIPTION
The AD8638 is a wide bandwidth auto-zero amplifiers
featuring rail-to-rail output swing while operating from 5 V to
16 V single supply or
+/2.5
V to ±8V dual supplies.
Using Analog Devices’ new topology these zero-drift
amplifiers combine low cost, with high accuracy and low
noise. No external capacitors are required. In addition, the
AD8638 family greatly reduces the digital switching noise
often found in chopper-stabilized amplifiers.
With an offset voltage of 10 μV, offset drift less than 0.08
μV/°C and noise of only 1.5 μVp-p (0 Hz to 10 Hz), the
AD8638 family is perfectly suited for applications where error
sources must be minimized. Position and pressure sensors,
thermocouple and thermopile detectors, and strain gage
amplifiers benefit greatly from nearly zero drift over their
operating temperature range.
The AD8638 family is specified for the extended industrial
(-40° to +125°C) temperature range. The AD8638 is available
in SOT-23 and SOIC.
