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.
