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.
