GENERAL D ESCRIP TIO N

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

operate from a 3 volt single supply as well as ±5 volt dual

supplies.

(P Suffix)

14-Lead SO

(S Suffix)

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.

OUTC

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.
