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 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.
