GENERAL DESCRIPTION

The AD8682 and AD8684 are dual and quad low power, precision

(1 mV) JFET amplifiers featuring excellent speed at 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 3.5 MHz. The JFET input stage

ensures bias current is typically a few picoamps and below

125 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-gain

stable and can drive higher capacity loads (G = 1, noninverting),

as an example of their excellent dynamic response over a wide

range of conditions, delivering dc precision performance at low

quiescent currents.
