Analog Devices OP181
The OP181, OP281 and OP481 are single, dual and quad ultralow power, single-supply amplifiers featuring rail-to-rail outputs. The output’s ability to swing rail-to-rail and not increase supply current, when the output is driven to a supply voltage, enables the OP181 family to be used as comparators in very low power systems. Fabricated on Analog Devices’ CBCMOS process, the OP181 family features a precision bipolar input and an output that swings to within millivolts of the supplies and continues to sink or source current all the way to the supplies.| Part No. | OP181 |
