Dear all, The need in using the two onboard DAC's of the Arduino Due created a question, which is what is the driver circuitry to use with the DAC's of the Arduino Due REv 3.0, or with DAC's in general. I've heard that it is not correct to connect DAC's driectly to something. Does anyone come acros…

Always connect a 2K Ohm resistor (safe above 1.1K) in serie with each DAC before connecting to a loud speaker. The maximum output current is 3 mA for DAC0 and DAC1.
