GENERAL DESCRIPTION

This family of amplifiers has ultralow offset, drift, and bias

current. The

AD8551, AD8552,

and

AD8554

are single, dual,

and quad amplifiers featuring rail-to-rail input and output swings.

All are guaranteed to operate from 2.7 V to 5 V with a single supply.

The

AD8551/AD8552/AD8554

provide the benefits previously

found only in expensive auto-zeroing or chopper-stabilized

amplifiers. Using Analog Devices, Inc. topology, these new

zero-drift amplifiers combine low cost with high accuracy. No

external capacitors are required.

With an offset voltage of only 1 μV and drift of 0.005 μV/°C, the

AD8551/AD8552/AD8554

are perfectly suited for applications

in which error sources cannot be tolerated. Temperature,

position and pressure sensors, medical equipment, and strain

gage amplifiers benefit greatly from nearly zero drift over their

operating temperature range. The rail-to-rail input and output

swings provided by the

AD8551/AD8552/AD8554

make both

high-side and low-side sensing easy.

The

AD8551/AD8552/AD8554

are specified for the extended

industrial/automotive temperature range (−40°C to +125°C).

The

AD8551

single amplifier is available in 8-lead MSOP and

8-lead narrow SOIC packages. The

AD8552

dual amplifier is

available in 8-lead narrow SOIC and 8-lead TSSOP surface-

mount packages. The

AD8554

quad is available in 14-lead

narrow SOIC and 14-lead TSSOP packages.
