DescriptionThe OPA145IDR operational amplifier (opamp)is a low-power JFET input amplifier thathas excellent drift, low current noise, and pico-ampere input bias current, makingthis device a suitable choice for amplifying smallsignals from high-impedance sensors. The rail-to-rail output swing interfaces 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 managementand take advantage of the single-supply, low-noise JFET architecture.
