32.3.2.3.2 Buffered Output

Enable the buffered analog output of the DAC by writing a ‘1’ to the Output Buffer Enable (OUTEN) bit in the Control A (DACn.CTRLA) register. Configure the output buffer range by writing to the Output Buffer Range (OUTRANGE) bit field in DACn.CTRLA. Refer to the Electrical Characteristics section for information about the drive capabilities of the DAC output buffer.

Note: To reduce power consumption, the DAC output pin should have its input disabled from the PORT peripheral. Refer to the I/O Multiplexing and Considerations section to determine which pin is used by the DAC output.
