34 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 two DAC modules. The DAC1 module has a buffered output that can be
connected to any of the designated DAC output pins. The DAC2 module has no output
pins or buffer, and the output is only connected internally to the ADC and CMP
modules.
