GENERAL DESCRIPTION
excellent speed at exceptionally low supply currents. The slew
rate is typically 9 V/s with a supply current of less than 250 A
per amplifier. These unity-gain stable amplifiers have a typical
gain bandwidth of 4 MHz.
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.
With a wide output swing (within 1.5 V of each supply), low
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.
temperature range. Th
e OP282 is available in the standard
8-lead, narrow SOIC and MSOP packages. Th
e OP482 isavailable in the PDIP and narrow SOIC packages, as well as
a 14-ball WLCSP.
