OP191/OP291/OP491
GE NE RAL DE SCRIPT ION
T he 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
operatefrom a 3 volt singlesupply as well as
±
5 volt 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 volts beyond either supply without any phase
inversion or latch-up. T he 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.
T he 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.
T he OP191/OP291/OP491 are specified over the extended
industrial (–40
°
C to +125
°
C) temperature range. T he OP191
single and OP291 dual amplifiers are available in 8-pin plastic
DIPs and SO surface mount packages. T he OP491 quad is
available in 14-pin DIPs and narrow 14-pin SO packages.
