The buffered DAC module consists of an internal reference DAC and an analog output buffer that is capable of driving an external load. An integrated pulldown resistor on the DAC output helps to provide a known pin voltage when the output buffer is disabled. This pulldown resistor cannot be disabled and remains as a passive component on the pin, even for other shared pin mux functions. Software writes to the DAC value register can take effect immediately or can be synchronized with PWMSYNC events.
Each buffered DAC has the following features:
The block diagram for the buffered DAC is shown in Figure 4-43.
