 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,

with statement:

analogWrite(DAC0, 0);

instead of 0 volt output I find 0,540 volt. It seems as an offset voltage.

Is it normal? Is my Arduino damaged?

How I can avoid such offset to obtain output of 0 Volt with input value = 0?

Thank you

Domenico

Yes, that's normal.
