12-bit Digital-to-Analog Converter (DAC)
34.1 Introduction
NOTE
For the chip-specific implementation details of this module's
instances see the chip configuration chapter.
The 12-bit digital-to-analog converter (DAC) is a low power general purpose DAC. The
output of this DAC can be placed on an external pin or set as one of the inputs to the
analog comparator, Op-Amps, ADC, or other peripherals.
34.2 Features
The DAC module features include:
• On-chip programmable reference generator output (voltage output from 1/4096 Vin
to Vin, step is 1/4096 Vin)
• Vin 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
