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.
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 × 1.3 mm × 0.55 mm) packages, while the
ADA4062-4 is available in lead-free, 14-lead TSSOP and
16-lead LFCSP packages.
