11.0
The Digital-to-Analog Converter supplies a variable
voltage reference, ratiometric with V
selectable output levels. The output of the DAC can be
configured to supply a reference voltage to the
following:
• DACOUT device pin
• Capacitive sensing modules
The Digital-to-Analog Converter (DAC) can be enabled
by setting the DACEN bit of the DACCON0 register.
EQUATION 11-1:
11.2
The DAC output voltage can be set to V
power consumption by setting the DACEN bit of the
DACCON0 register to ‘0’.
11.3
The DAC is V
changes with fluctuations in V
accuracy of the DAC can be found in Section 25.0
“Electrical Specifications”.
11.4
The DAC can be output to the device DACOUT pin by
setting the DACOE bit of the DACCON0 register to ‘1’.
Selecting the reference voltage for output on the
DACOUT pin automatically overrides the digital output
buffer and digital input threshold detector functions of
that pin. Reading the DACOUT pin when it has been
configured for reference voltage output will always
return a ‘0’.

11.1
The DAC has 32 voltage level ranges. The 32 levels
are set with the DACR<4:0> bits of the DACCON1
register.
The DAC output voltage is determined by the following
equation:
Due to the limited current drive capability, a buffer must
be used on the voltage reference output for external
connections to DACOUT. Example 11-1 shows an
example buffering technique.
11.5
When the device wakes up from Sleep through an
interrupt or a Watchdog Timer time-out, the contents of
the DACCON0 register are not affected. To minimize
current consumption in Sleep mode, the voltage
reference should be disabled.
11.6
A device Reset affects the following:
• Voltage reference is disabled
• Fixed voltage reference is disabled
• DAC is removed from the DACOUT pin
• The DACR<4:0> range select bits are cleared
