GENERAL DESCRIPTIONThe 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 are specified at +3V and +5V
single supply as well as ±5V 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
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 250ms.
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.
The OP481 quad amplifier is available in narrow 14-lead SOIC
and TSSOP packages.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposures to absolute maximum rating
conditions for extended periods may affect device reliability.
*qJA is specified for the worst-case conditions, i.e., qJA is specified for device
soldered in circuit board for TSSOP and SOIC packages.
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
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.
