5-BIT DIGITAL-TO-ANALOG

CONVERTER (DAC) MODULE

The Digital-to-Analog Converter supplies a variable

voltage reference, ratiometric with the input source,

with 32 selectable output levels.

The positive input source (VSOURCE+) of the DAC can

be connected to:

•External VREF+ pin

•VDD supply voltage

The negative input source (VSOURCE-) of the DAC can

be connected to:

•Vss

The output of the DAC (DACx_output) can be selected

as a reference voltage to the following:

• Comparator positive input

• ADC input channel

•DACxOUT1 pin

•DACxOUT2 pin

The Digital-to-Analog Converter (DAC) can be enabled

by setting the DACEN bit of the DACxCON0 register.
