3 Description
The OPA140, OPA2140, and OPA4140 operational
amplifier (op amp) family is a series of low-power
JFET input amplifiers that features good drift and low
input bias current. The rail-to-rail output swing and
input range that includes Vâ 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 OPA140 achieves 11-MHz unity-gain bandwidth
and 20-V/μs slew rate while consuming only 1.8 mA
(typical) of quiescent current. It runs on a single 4.5-V
to 36-V supply or dual ±2.25-V to ±18-V supplies.
All versions are fully specified from â40°C to 125°C
for use in the most challenging environments. The
OPA140 (single) is available in the 5-pin SOT-23, 8-
pin VSSOP, and 8-pin SOIC packages; the OPA2140
(dual) is available in both 8-pin VSSOP and 8-pin
SOIC packages; and the OPA4140 (quad) is
available in the 14-pin SOIC and 14-pin TSSOP
packages.
