This field is valid only when channel_cfg_dt_node_exists is set to true.

channel_cfg_dt_node_exists

bool dac_dt_spec::channel_cfg_dt_node_exists

Flag indicating whether configuration of the associated DAC channel is provided as a child node of the corresponding DAC controller in devicetree.

channel_id

uint8_t dac_dt_spec::channel_id

DAC channel identifier used by this io-channel.

dev

const struct device* dac_dt_spec::dev

Pointer to the device structure for the DAC driver instance used by this io-channel.

vref_mv

uint16_t dac_dt_spec::vref_mv

Voltage of the reference selected for the channel or 0 if this value is not provided in devicetree.

This field is valid only when channel_cfg_dt_node_exists is set to true.
