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

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-
