GENERAL DESCRIPTION
IN A 3

The OP282/OP482 dual and quad operational amplifiers feature
excellent speed at exceptionally low supply currents. Slew rate
exceeds 7 V/µs with supply current under 250
µA
per amplifier.
These unity gain stable amplifiers have a typical gain bandwidth
of 4 MHz.
The JFET input stage of the OP282/OP482 ensures bias current
is typically a few picoamps and below 500 pA over the full tem-
perature range. Offset voltage is under 3 mV for the dual and
under 4 mV for the quad.
With a wide output swing, within 1.5 V of each supply, low
power consumption, and high slew rate, the OP282/OP482 are
ideal for battery powered systems or power restricted applica-
tions. An input common-mode range that includes the positive
supply makes the OP282/OP482 an excellent choice for high-
side signal conditioning.
The OP282/OP482 are specified over the extended industrial
temperature range. Both dual and quad amplifiers are available
in plastic DIP plus SOIC surface mount 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 OP282/OP482 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.
WARNING!
