GENERAL DESCRIPTION

This new 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 single supply.

The AD855x family provides the benefits previously found only

in expensive autozeroing or chopper-stabilized amplifiers. Using

Analog Devices’ new 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 is perfectly suited for applications where error

sources cannot be tolerated. Temperature, position and pres-

sure 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 AD855x family make both high-side and low-

side sensing easy.

The AD855x family is specified for the extended industrial/

automotive (–40

°C to +125°C) temperature range. The AD8551

single is available in 8-lead MSOP and narrow 8-lead SOIC

packages. The AD8552 dual amplifier is available in 8-lead

narrow SO and 8-lead TSSOP surface mount packages. The

AD8554 quad is available in narrow 14-lead SOIC and 14-lead

TSSOP packages.
