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.
