The device supports a low-power shutdown mode in which the entire internal circuitry is powered down. In shutdown mode, the total power consumption of the device is typically equal to 1 μW.

In order to enter shutdown mode, the STBY input pin must be set to logic low and the RANGE input pin must be set to a logic low value. The device can be asynchronously put into this mode by configuring the STBY and RANGE inputs at any time during device operation.

The device exits shutdown mode when a logic high input is applied to the STBY pin. At this time, the internal circuitry starts powering up and takes a minimum time of 13 ms to settle in external reference mode before the next conversion can be initiated. After recovery from shutdown mode, a RESET signal must be applied before the next conversion can be initiated. See the Timing Requirements: Exit Shutdown Mode table and Figure 6-9 for timing details.
