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.
