    Power-Down
    Choosing Power-Down Mode
    You can save power by placing the converter in a
    low-current shutdown state between conversions.
    Select full power-down or fast power-down mode via
    bits 1 and 0 of the DIN control byte with
     SHDN
     either
    high or floating (see Tables 3 and 6). Pull
     SHDN
     low at
    any time to shut down the converter completely.
     SHDN
    overrides bits 1 and 0 of DIN word (see Table 7).
    Full power-down mode turns off all chip functions that
    draw quiescent current, typically reducing I
    DD
    to 2μA. 
    Fast power-down mode turns off all circuitry except the
    bandgap reference. With the fast power-down mode, the
    supply current is 30μA. Power-up time can be shortened
    to 5μs in internal compensation mode. 
    In both software shutdown modes, the serial interface
    remains operational, however, the ADC will not convert.
    Table 5 illustrates how the choice of reference-buffer
    compensation and power-down mode affects both
    power-up delay and maximum sample rate. 
    In external compensation mode, the power-up time is
    20ms with a 4.7μF compensation capacitor when the
    capacitor is fully discharged. In fast power-down, you
    can eliminate start-up time by using low-leakage capaci-
