AD8684

The AD8682 and AD8684 are dual and quad low power, precision (1 mV) JFET amplifiers featuring excellent speed at ow supply currents. The slew rate is typically 9 V/s with a supply current under 250 A per amplifier. These unity-gain able amplifiers have a typical gain bandwidth of 3.5 MHz. The JFET input stage ensures bias current is typically a few coamps and below 125 pA maximum over the full temperature operating range.

The devices AD8682 and AD8684 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 sponse over a wide range of conditions, delivering dc precision performance at low quiescent currents.
