AD8682ARMZ-REEL:  Dual Low Power, High Speed JFET Operational Amplifier MSOP-8封装

AD8682AD8684分别是双路和四路低功耗、精密(1 mV)JFET放大器,具有出色的速度和低电源电流特性。典型压摆率为9 V/µs,每个放大器的电源电流低于250 µA。这些单位增益稳定型放大器的典型增益带宽为3.5 MHz。JFET输入级则可确保典型偏置电流仅数pA,且在整个工作温度范围内均小于125 pA。

上述器件非常适合便携式、低功耗应用,特别是较高源阻抗应用。两款放大器的单位增益稳定,可以驱动较高的容性负载(G = 1、同相),在各种条件下均具有出色的动态响应范围,并且能以低静态电流提供直流精度性能。

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.
