37 DAC - Digital-to-Analog Converter Module

The Digital-to-Analog Converter (DAC) supplies a variable voltage reference, ratiometric with the input source, with programmable selectable output levels.

The positive and negative input references (DACxREF+ and DACxREF-) can each be selected from several sources.

The output of the DAC (DACxOUTn) can be selected as a reference voltage to several other peripherals or routed to output pins.

The Digital-to-Analog Converter (DAC) is enabled by setting the EN bit.

Important: Each DAC module has a buffered output that can be connected to any of the designated DAC output pins. The DAC modules are also connected internally to the ADC, OPA, and CMP modules.
