OP191/OP291/OP491
GENERAL DESCRIPTION
The OP191, OP291, and OP491 are single, dual and quad
micropower,
single-supply, 3 MHz bandwidth amplifiers fea-
turing rail-to-rail inputs and outputs. All are guaranteed to
operate from a 3 V single supply as well as
±
5 V dual supplies.
Fabricated on Analog Devices’ CBCMOS process, the OP191
family has a unique input stage that allows the input voltage to
safely extend 10 V beyond either supply without any phase inver-
sion or latch-up. The output voltage swings to within millivolts
of the supplies and continues to sink or source current all the
way to the supplies.
Applications for these amplifiers include portable telecom
equipment, power supply control and protection, and interface
for transducers with wide output ranges. Sensors requiring a
rail-to-rail input amplifier include Hall effect, piezo electric, and
resistive transducers.
The ability to swing rail-to-rail at both the input and output
enables designers to build multistage filters in single-supply
systems and maintain high signal-to-noise ratios.
The OP191/OP291/OP491 are specified over the extended
industrial (–40
°
C to +125
°
C) temperature range. The OP191
single and OP291 dual amplifiers are available in 8-lead plastic
SO surface mount packages
*
. The OP491 quad is available in
14-lead DIPs and narrow 14-lead SO packages. Consult factory
for OP491 TSSOP availability.
*
The OP291 dual is also available in 8-lead Plastic Dip.
