V– 4 Fabricated on Analog Devices’ CBCMOS process, the
OP281/OP481 feature a precision bipolar input and an output
that swings to within millivolts of the supplies, continuing to
sink or source current up to a voltage equal to the supply voltage.
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
the OP281/OP481 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 OP281/OP481 are specified over the extended industrial
temperature range (−40°C to +85°C). The OP281 dual amplifier
is available in 8-lead SOIC surface-mount and TSSOP packages. …
