    Hi Nightingale,

    Snubbing resistors on the VREFHI capacitors should be 100m (0.1 ohms) not 100M (100 Million Ohms).

    Nominal values of the ADC input capacitors should be 20x Ch = about 330pF (unless you are sampling very slow on each channel, in which case about 100nF is appropriate).

    This is not a comprehensive review, just some misc. comments about the ADC sections.
