Description

The OP181, OP281 and OP481 are single, dual and quadultralow 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 th-at swings to within millivolts of the supplies and continues to sink or source current all the way to the supplies.

Applications for these amplifiers OP181, OP281 and OP481 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 voltag-e, enables the OP181 family to be used as comparators in very low power systems. This is enhanced by their fast at-uration recovery time. Propagation delays are 250 s.

The OP181/OP281/OP481 are specified over the extended industrial (40°C to +85°C) temperature range. The OP1-81, 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 14-pin DIPs, narrow 14-pin SO and TSSOP ackages.

The OP281 and OP481 are dual and quad ultralow power single-supply amplifiers featuring rail-to-rail outputs. Each operates from supplies as low as 2.0 V and is specified at +3 V and +5 V single
