OPAx145 JFET Operational Amplifiers

Texas Instruments OPAx145 JFET Operational Amplifiers are low-power JFET input amplifiers that feature excellent drift, low current noise, and pico-ampere input bias current. These features make these devices suitable for amplifying small signals from high-impedance sensors. The rail-to-rail output swings to modern, single-supply, precision analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). In addition, the input range that includes V– allows designers to simplify power management and take advantage of the single-supply, low-noise JFET architecture.
