DESCRIPTION
The OPA140A operational amplifier is a low-power JFET input amplifier that features 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 OPA140A runs on a single 4.5-V to
36-V supply or dual ±2.25-V to ±18-V supplies.

Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality
Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room
temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not
warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
