Hello everybody!

I have a very basic question, surely
I am using the DAC pin of an arduino due, which supplies a voltage between 0.55V and 3.3V, and I want it to supply a voltage between 0V and 5V. how can I do this? Is it possible at least that it supplies between 0V and 3.3V ?. that is, only lower the minimum voltage to 0V?

thanks

 

All you have to do is to re-scale the value that is used to set the output voltage in the code.
Output voltage = (Input voltage - 0.55) X 5 / 3.3
