    What is the equivalent input network for the LTC2208? I would like to simulate a differential driver amp, anti-aliasing filter, and the LTC2208 input. These articles shows equivalent networks for some ADC's
    www.analog.com/.../designing-high-speed-analog-signal-chains.html
    www.analog.com/.../wideband-adc-design-considerations-2.html
    

    The LTC2208 datasheet shows an equivalent network in Figure 2, but it includes some diodes and FETs, which I don't know how to model in an AC simulation.
