GENERAL DESCRIPTION
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 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
temperature 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
applications. 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 PDIP and narrow SOIC packages.
