GENERAL DESCRIPTION
The OP181, OP281 and OP481 are single, dual and quad ultralow power, single-supply amplifiers featuring rail-to-rail outputs. All operate from supplies as low as 2.0 V and are specified at +3 V and +5 V single supply as well as ± 5 V dual supplies. 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. Applications for these amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interface for transducers in very low power systems. The output’s ability to swi……
