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 AD855x family provides 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
AD855x 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
AD855x family make both high-side and low-side sensing easy.
The AD855x family is specified for the extended industrial/auto
motive 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.
