AD8682ARMZ-R2 GENERAL DESCRIPTION

The AD8682 and AD8684 are dual and quad low power, precision(1 mV) JFET amplifiers featuring excellent speed at low supplycurrents. The slew rate is typically 9 V/μs with a supply currentunder 250 μA per amplifier. These unity-gain stable amplifiershave a typical gain bandwidth of 3.5 MHz. The JFET input stageensures bias current is typically a few picoamps and below125 pA maximum over the full temperature operating range.The devices are ideal for portable, low power applications,especially with high source impedance. The devices are unity-gainstable and can drive higher capacity loads (G = 1, noninverting),as an example of their excellent dynamic response over a widerange of conditions, delivering dc precision performance at lowquiescent currents.
