Each operates 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 OP281/OP481 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 interfacing for transducers in very low power systems. The output’s ability to swing rail-to-rail and not increase supply current, when the output is driven to a supply voltage, enables th……
