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.
