GENERAL DESCRIPTION

AD8628

This new family of amplifiers has ultra-low offset, drift and bias

current. The AD8628 is a wide bandwidth auto-zero amplifier

featuring rail-to-rail input and output swings and low noise.

Operation is fully specified from 2.7 to 5 volts single supply

(±1.35V to ±2.5V dual supply).

The AD8628 family provides the benefits previously found only

in expensive auto-zeroing or chopper-stabilized amplifiers.

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 AD8628

greatly reduces the digital switching noise found in most

chopper stabilized amplifiers.

With an offset voltage of only 1µV, drift less than 0.005 µV/°C

and noise of only 0.5uV P-P (0Hz to 10 Hz) the AD8628 is

perfectly suited for applications where error sources cannot be

tolerated. Position and pressure sensors, medical equipment, and

strain gage amplifiers benefit greatly from nearly zero drift over

their operating temperature range. Many systems may take

advantage of the rail-to-rail input and output swings provided by
