Very Low Offset Drift: 1mV/°C max
The OPA140, OPA2140, and OPA4140 op amp
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
Very Low Offset: 120mV
Low Input Bias Current: 10pA max
Very Low 1/f Noise: 250nVPP, 0.1Hz to 10Hz
Low Noise: 5.1nV/√Hz
Slew Rate: 20V/ms

and
Low Supply Current: 2.0mA max
Input Voltage Range Includes V– Supply
Single-Supply Operation: 4.5V to 36V
Dual-Supply Operation: ±2.25V to ±18V
No Phase Reversal
digital-to-analog converters (DACs).
The OPA140 achieves 11MHz 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
OPA140 (single) is available in the SOT23-5,
MSOP-8, and SO-8 packages; the OPA2140 (dual) is
available in both MSOP-8 and SO-8 packages; and
the OPA4140 (quad) is available in the SO-14 and
TSSOP-14 packages.
