Ok.
Thank you wibauxl.

"I tried the DACC on the Arduino Due, but it doesn't work as expected. I used the function analogWrite() for setting a new DAC value. The following code will work as expected:"

Code:

byte value;
void loop() {
  analogWrite(DAC0, value++);
}

Hello, when i test the DAC on the DUE i measured an Outputvoltage from 0,55V (value 0) to 2,77V (value 255). I thought the DAC has a range from 0V to 3,3V?! Do anybody knows more or can help me?
