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
卤
5 V dual
supplies.
Fabricated on Analog Devices鈥?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鈥檚 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
碌s.
The OP181/OP281/OP481 are specified over the extended
industrial (鈥?0掳C to +85掳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 14-
pin DIPs, narrow 14-pin SO and TSSOP packages.
