5 DAC in Power-Down Modes

In the Power-Saving Operation modes (Sleep, Idle, and Doze) of the PIC microcontroller, we may expect changes in current consumption when using the DAC.

When the device wakes up from Sleep mode by an interrupt or by a Windowed Watchdog Timer (WWDT) time-out, the contents of the DACxCON0 register are not affected.

Tip:
  1. To minimize the current consumption in Sleep mode, the voltage reference must be disabled from the FVR before the controller enters Power-Down mode.
  2. Refer to the device-specific data sheet for more details about Power-Saving Operation modes, DAC, FVR, and corresponding registers.
