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 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. This is enhanced by their fast saturation recovery time. Propagation delays are 250 µs. The OP181/OP281/OP481 are specified over the extended industrial (40°C to +85°C) temperature range. The OP181, single, and OP281, dual, amplifiers are available in 8-pin plastic DIPs and SO surface mount packages. The OP281 is also available in 8-lead TSSOP. The OP481 quad is available in 14pin DIPs, narrow 14-pin SO and TSSOP packages.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP181/OP281/OP481 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
