OPA140 datasheet



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 ow-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 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.
