ADC spice simulation.

Hi all,

     I want to use ADC to run some simulations in TINA-TI.  However, I cannot find the output pin in the spice model. It will be very helpful if you tell me where the outputs are.

     Here are the spice model and reference design from TI.

Best Regards,

Feiran

    Feiran,

    The purpose of this model is to show the loading of the ADC to the signal buffer, so one can tell if the amplifier selected is capable enough to send the input signal to the ADC without losing too much fidelity.

    It will also show the noise introduced by the switching of the sampling circuit in the ADC.

    It does not model the conversion, hence there's no output pin.

    Thanks,
    JC
