GENERAL DESCRIPTION
OP482
11 V–
The OP282/OP482 dual and quad operational amplifiers feature
excellent speed at exceptionally low supply currents. The slew
rate is typically 9 V/µs with a supply current of less than 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 that the bias
current is typically a few picoamps and is less than 500 pA over
the full temperature range. The offset voltage is less than 3 mV
for the dual amplifier and less than 4 mV for the quad amplifier.

OP482
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. The OP282 is available in the standard
8-lead, narrow SOIC and MSOP packages. The OP482 is
available in the PDIP and narrow SOIC packages, as well as
a 14-ball WLCSP.
