GENERAL DESCRIPTION
The OP191, OP291, and OP491 are single, dual, and quad
micropower, single-supply, 3 MHz bandwidth amplifiers
featuring rail-to-rail inputs and outputs. All are guaranteed to
operate from a +3 V single supply as well as 鹵5 V dual supplies.
Fabricated on Analog Devices CBCMOS process, the OPx91
family has a unique input stage that allows the input voltage to
safely extend 10 V beyond either supply without any phase
inversion 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 tele-
communications 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.

Information furnished by Analog Devices is believed to be accurate and reliable. However, no
responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other
rights of third parties that may result from its use. Specifications subject to change without notice. No

The ability to swing rail-to-rail at both the input and output
enables designers to build multistage filters in single-supply
systems and to maintain high signal-to-noise ratios.
The OP191/OP291/OP491 are specified over the extended
industrial 鈥?0擄C to +125擄C temperature range. The OP191
single and OP291 dual amplifiers are available in 8-lead plastic
SOIC surface-mount packages. The OP491 quad is available in a
14-lead PDIP, a narrow 14-lead SOIC package, and a 14-lead
TSSOP.
