... 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 ...
