Product Summary
The OP491GS is a single-supply, 3 MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. All are guaranteed to operate from a 3 volt single supply as well as ±5 volt dual supplies. Fabricated on Analog Devices’ CBCMOS process, the OP491GS 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 applications of the OP491GS are Industrial Process Control, Battery Powered Instrumentation, Power Supply Control and Protection, Telecom, Remote Sensors, Low Voltage Strain Gage Amplifiers, DAC Output Amplifier.
