Texas Instruments OPA817 High Precision Operational Amplifier (Op Amp) 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 with a wide gain bandwidth of 400MHz and a supply range from 6V to 12.6V. The fast slew rate of 1000V/µs allows a low distortion and wide large-signal bandwidth when used as a high-impedance buffer in high-speed digitizers, active probes, and other test and measurement applications.The Texas Instruments OPA817 offers an extremely low input offset voltage of ±250µV and offset voltage drift of ±3.5µV/°C. The combination of pico-amperes of input bias current and low input voltage noise (4.5nV/√Hz) makes the OPA817 an ideal wideband transimpedance amplifier in optical test and communication equipment 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.
