The OPA817 is a high-voltage, unity-gain-stable, 400-MHz gain-bandwidth product (GBWP), voltage-feedback operational amplifier (op amp) featuring a 4.5-nV/√Hz, low-noise, JFET input stage. The low offset voltage (250 μV maximum), offset voltage drift (3.5 μV/°C maximum), and unity gain bandwidth of 800 MHz makes this device an excellent choice for high-input-impedance, high-speed, data-acquisition front-ends. The high voltage capability combined with 1000 V/µs slew rate enables applications needing wide output swings (9 V_PP at V_S = 12 V) for high-frequency signals such as those often found in medical instrumentation, optical front-end, test, and measurement applications. The low noise JFET input with pico-amperes of bias current makes the device attractive in high-gain TIA applications and in test and measurement front-ends. OPA817 also features a power-down mode that disables the core amplifier for power savings.

The OPA817 is built using TI's proprietary high-voltage, high-speed, complementary bipolar SiGe process.
