Each DAC has one continuous output with high drive capabilities for both resistive and capacitive loads. It is also
possible to split the continuous time channel into two Sample and Hold (S/H) channels, each with separate data
conversion registers.
A DAC conversion may be started from the application software by writing the data conversion registers. The DAC can
also be configured to do conversions triggered by the Event System to have regular timing, independent of the
application software. DMA may be used for transferring data from memory locations to DAC data registers.
The DAC has a built-in calibration system to reduce offset and gain error when loading with a calibration value from
software.
PORTA and PORTB each has one DAC. Notation of these peripherals are DACA and DACB. respectively.
