GENERAL DESCRIPTION

The ADA4062-2 is a dual JFET-input amplifier with industry-

leading performance. It offers lower power, offset voltage, drift

and ultralow bias current. The ADA4062-2 B grade features typical

low offset voltage of 0.5 mV, offset drift of 4 μV/°C, and bias current

of 2 pA. The ADA4062-2 is ideal for various applications, including

process control, industrial and instrumentation equipment, active

filtering, data conversion, buffering, and power control and

monitoring. With a low supply current of 165 μA per amplifier,

it is also very well suited for lower power applications. The

ADA4062-2 is specified for the extended industrial temperature

range of −40°C to +125°C and is available in lead-free SOIC and

MSOP packages.
