Introduction

AI Translation

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 ±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 telecommunications 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 to maintain high signal-to-noise ratios.

The OP191/OP291/OP491 are specified over the extended industrial -40°C to +125°C temperature range.
