Texas Instruments OPA145
The OPA145 and OPA2145 (OPAx145) devices are part of a family of low-power JFET input amplifier that have excellent drift, low current noise, and picoampere input bias current. These features make the OPAx145 an excellent 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).| Part No. | OPA145 |
