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.
