12-bit Digital-to-Analog Converter (DAC)
18.1 Introduction
NOTE
For the chip-specific implementation details of this module's
instances, see the chip configuration information.
The 12-bit digital-to-analog converter (DAC) is a low-power, general-purpose DAC. The
output of the DAC can be placed on an external pin or set as one of the inputs to the
analog comparator, op-amps, or ADC.
18.2 Features
The features of the DAC module include:
• On-chip programmable reference generator output. The voltage output range is from
1⁄4096 V
in
to V
in
, and the step is 1⁄4096 V
in
, where V
in
is the input voltage.
• V
in
can be selected from two reference sources
• Static operation in Normal Stop mode
• 16-word data buffer supported with configurable watermark and multiple operation
modes
• DMA support
