GENERAL DESCRIPTION
This new family of amplifiers has ultralow offset, drift and bias
current. The AD8571, AD8572 and AD8574 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 AD857x 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.) In
addition, using a patented spread-spectrum autozero technique, the
AD857x family virtually eliminates the intermodulation effects from
interaction of the chopping function with the signal frequency in ac
applications.
With an offset voltage of only 1
μ
V and drift of 0.005
μ
V/
°
C, the
AD8571 is perfectly suited for applications where error sources
cannot be tolerated. Position, and pressure sensors, medical
equipment, and strain gage amplifiers benefit greatly from nearly
zero drift over their operating temperature range. Many more
systems require the rail-to-rail input and output swings provided
by the AD857x family.
The AD857x family is specified for the extended industrial/automotive
(–40
°
C to +125
°
C) temperature range. The AD8571 single is
available in 8-lead MSOP and narrow 8-lead SOIC packages. The
AD8572 dual amplifier is available in 8-lead narrow SO and 8-lead
TSSOP surface mount packages. The AD8574 quad is available in
narrow 14-lead SOIC and 14-lead TSSOP packages.
