    Ok,

    after looking at 65472 in binary 1111111111000000

    It appears that you have just shifted a 10 bit binary to the Left end of a 16 bit number.

    So then the AD value for a 16-bit DT_Analog can range from 0-65472 ??
    Therefore we get to take advantage of the extra 6 bits of resolution EXCEPT when the value goes over 65472 ??
    We just give up a little resolution to gain the extra (almost) 6 bits over a 10 bit AD ??

    and 8 bit range is still 0-255
    and 10 bit range is still 0-1023
