44 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 (DAC1OUTx) 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: This family of devices has one DAC module. The DAC module has two buffered outputs that can be connected to any of the designated DAC output pins. The module is also connected internally to select peripherals.
