  • How to modify analog output range of Arduino Due 16 days ago

    Hi David, I think with this circuit you want to set the values of an analog pid, why don't you make a digital pid with Arduino Due with analog output? In another post I also made the design of a bipolar output.
    Returning to my circuit, with regard to the output of the LM358, since it is powered by single power, it can never have a zero output, but there will be a difference of a few millivolts. In essence, for values close to zero there will be errors.

    Hi David, thank you for appreciation. Answering the first question, I would say yes, though I have never tried two dacs. You have to build two equal circuits (one LM358 for both) with gain G = 4 /2.2 = 1.82, so resistors R2 = 182 k , that is also a standard E96 value.

    sorry, I can't help you because I don't know that board
