# DAC as Source For Internal Peripherals

The analog output of the DAC is internally connected to both the AC and the ADC and is available to these peripherals when the DAC is enabled (ENABLE = ‘1’ in DACn.CTRLA). When the DAC analog output is only being used internally, it is not necessary to enable the pin output driver (i.e., OUTEN = ‘0’ in DACn.CTRLA is acceptable).
