ATxmega128A1U/ATxmega64A1U
A DAC conversion is automatically started when new data to be converted are available. Events from the event system can
also be used to trigger a conversion, and this enables synchronized and timed conversions between the DAC and other
peripherals, such as a timer/counter. The DMA controller can be used to transfer data to the DAC.
The DAC has high drive strength, and is capable of driving both resistive and capacitive loads, aswell as loads which com-
bine both. A low-power mode is available, which will reduce the drive strength of the output.
Internal and external voltage references can be used. The DAC output is also internally available for use as input to the
analog comparator or ADC.
PORTA and PORTB each has one DAC. Notation of these peripherals are DACA and DACB, respectively.
