7.4 Device Functional Modes

7.4.1 Shutdown Mode

In addition to the two conversion modes (continuous and triggered), the device also has a shutdown mode

(selected by the MODE bits in ADC_CONFIG register) that reduces the quiescent current to less than 5 µA and

turns off current into the device inputs, reducing the impact of supply drain when the device is not being used.

The registers of the device can be written to and read from while the device is in shutdown mode. The device

remains in shutdown mode until another triggered conversion command or continuous conversion command is

received.

The device can be triggered to perform conversions while in shutdown mode. When a conversion is triggered,

the ADC will start a conversion. After the conversion is complete, the device will return to the shutdown state.

Note that the shutdown current is specified with an inactive communications bus. Active clock and data activity

will increase the current consumption as a function of the bus frequency.

7.4.2 Power-On Reset

Power-on reset (POR) is asserted when VS drops below 1.26 V (typical) at which all of the registers are reset to

their default values. A manual device reset can be initiated by setting the RST bit in the CONFIG register. The

default power-up register values are shown in the reset column for each register description. See Register Maps

for the register descriptions.
