The OPA817 is a unity-gain stable, voltage-feedback operational amplifier for high-speed, high-precision and wide dynamic range applications.

The OPA817 has a low-noise junction gate field-effect transistor (JFET) input stage that features a wide gain-bandwidth of 400-MHz and a supply range from 6-V to 12.6-V. The fast slew rate of 1000-V/µs allows a wide large-signal bandwidth and low distortion when used as high impedance buffer in high-speed digitizers, active probes and other test and measurement applications.

The OPA817 offers extremely low input offset voltage of ±250-µV and offset voltage drift of ±3.5-µV/°C. The combination of pico-amperes of input bias current and low input voltage noise (4.5-nV/√Hz) makes the OPA817 an ideal wideband transimpedance amplifier in optical test and communication equipment as well as medical and scientific instrumentation.

The OPA817 is available in an 8-lead WSON package with an exposed thermal pad for heat dissipation. This device is specified to operate over the industrial temperature range of –40°C to +105°C.
