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.
