    Which of the following is
    1. Fastest Analog to Digital converter
    2. Most accurate Analog to digital converter
    the options are
    a. Counter type Analog to digital converter
    b. Successive Approximation Method(SAR)
    c. Dual slope integration Analog to digital converter
    d. Flash type Analog to digital converter
    The two questions above may have same or different choice.
    Please help. Choose from the given 4 options only.

    Also if the output of 8-bit dual slope is (10011100) and reference voltage is 5V then what is the input.
    Can anyone help

    The fastest D/A converter should be the flash type A/D.
    The most accurate could be the dual slope integration A/D, depending on how the converter is configured.

    The output of the A/D should be the same as the other types; the input would be 10011100 over 256 time 5 volts.
