14-Pin Flash, 8-Bit Microcontrollers

Microchip Technology 

PIC16(L)F1503

16.0 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.
