The OP181/OP281/OP481 is a single-supply, ultralow power, integrated circuit. Features include a wide input voltage range, low supply current, rail-to-rail output swing, and no phase reversal. This product is widely used in safety monitoring, battery powered instrumentation, remote sensors and low voltage strain gage amplifiers.
The OP181, OP281, and OP481 are single, dual, and quad ultralow power, single-supply amplifiers featuring rail-to-rail outputs. Fabricated on Analog Devices' CBCMOS process, these devices feature a precision bipolar input and an output that swings to within millivolts of the supplies. They are specified over the extended industrial temperature range of –40 °C to +85 °C.
