9.2.1 High Input Impedance, 200 MHz, Digitizer Front-End Amplifier Design

The OPA817 offers a wide large-signal bandwidth, high-slew rate along with high-input impedance making it ideal for data acquisition systems. The trimmed DC precision of the OPA817 enables its use directly as front-end amplifier where low offset and offset voltage drift is needed.
