What is the input impedance requirement?

Does high-edge MOS feedback affect the input impedance?

    Hello,

    This device uses a switch capacitor circuit to sample the input. 

    Usually SAR devices are driven by an op amp with an RC following then to the ADC analog input. 

    This device though is an 8bit device, thus it is possible to not need an op amp. Would you please share your input drive circuit for review. 

    Regards
