Product Summary

The OP291 is a single, dual and quad micropower, single-supply, 3 MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. It is guaranteed to operate from a 3 volt single supply as well as ±5 volt dual supplies. Fabricated on Analog Devices CBCMOS process, the OP291 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. The output voltage swings to within millivolts of the supplies and continues to sink or source current all the way to the supplies. The applications of the OP291 include Industrial Process Control, Battery Powered Instrumentation, Power Supply Control and Protection, Telecom, Remote Sensors, Low Voltage Strain Gage Amplifiers, DAC Output Amplifier.
