DESCRIPTION
The OPA141, OPA2141, and OPA4141 amplifier
family is a series of low-power JFET input amplifiers
that feature good drift and low input bias current. The
rail-to-rail output swing and input range that includes
V– allow designers to take advantage of the
low-noise characteristics of JFET amplifiers while
also interfacing to modern, single-supply, precision
analog-to-digital converters (ADCs) and
digital-to-analog converters (DACs).
The OPA141 achieves 10MHz unity-gain bandwidth
and 20V/ms slew rate while consuming only 1.8mA
(typ) of quiescent current. It runs on a single 4.5 to
36V supply or dual ±2.25V to ±18V supplies.
All versions are fully specified from –40°C to +125°C
for use in the most challenging environments. The
OPA141 (single) and OPA2141 (dual) versions are
available in both MSOP-8 and SO-8 packages; the
OPA4141 (quad) is available in the SO-14 and
TSSOP-14 packages.
