The OPA145, OPA2145, and OPA4145 operational amplifier (op amp) family is a series of
low-power JFET input amplifiers that feature excellent drift, low current noise, and pico-ampere
input bias current, making these devices a suitable choice for amplifying small signals 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 management and take advantage
of the single-supply, low-noise JFET architecture.
