ADA4062-2ARZ-R7

微型，低功耗JFET输入运算放大器 Tiny, Low Power JFET-Input Op Amp

GENERAL DESCRIPTION

The ADA4062-2 and ADA4062-4 are dual and quad JFET-input amplifiers with industry-leading performance. They offer lower power, offset voltage, drift, and ultralow bias current. The ADA4062-2 B grade SOIC package features a typical low offset voltage of 0.5 mV, an offset drift of 5 μV/°C, and a bias current of 2 pA.

The ADA4062 family is ideal for various applications, including process controls, industrial and instrumentation equipment, active filtering, data conversion, buffering, and power control and monitoring. With a low supply current of 165 μA per amplifier, they are well suited for lower power applications.
