ADA4062-2 Op Amp IC Chip

ADA4062-2(Low Power JFET-Input Op Amp)

Introduction

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.

The ADA4062 family is also specified for the extended industrial temperature range of -40°C to +125°C. The ADA4062-2 is available in lead- free, 8-lead SOIC, 8-lead MSOP, and 10-lead LFCSP (1.6 mm X 1.3 mm X 0.55 mm) packages, while the ADA4062-4 is available in lead-free, 14-lead TSSOP and 16-lead LFCSP packages.
