AD8554ARZ-REEL7 Zero-Drift Amplifier 4 Circuit Rail-to-Rail 14-SOIC
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
surfacemount packages. The AD8554 quad is available in 14-lead
narrow SOIC and 14-lead TSSOP packages
