The device immediately starts a conversion after a power-on sequence and provides the first result

after conversion time TS. A higher power consumption occurs during the actual conversion while the

device stays in the standby mode after a finished conversion until the next conversion is activated as

shown in the following figure.

Sleep Mode

The sleep mode is activated by setting the bit SM in the configuration register to 1. This shuts the

device down immediately and reduces the power consumption to a minimum value.

Entering the sleep mode will take some time (120 ms maximum) and the first conversion after the

sleep mode takes longer than the values specified in Figure 6. Therefore, it is recommended to trigger

a single shot conversion at the same time while entering sleep mode. After 150ms, the device enters

the sleep mode and subsequent conversion times are as specified in Figure 6.

The serial interface is the only active circuitry in the sleep mode in order to provide access to the

digital registers.

After resetting the SM bit to 0, the device enters the continuous conversion mode.
