                 Hello first I want to ask if it makes sense to use dual 3.3V supply for digital    (one for each board)  I have two ISO7240M isolators which I intend to use with two COD Dacs.It makes sense to use both?  if I use a single isolator for both boards from where do I get him powered on the dac side ? thank you |

                You could - but I personally would not, unless they are physically far apart. |

                Thank you Russ for your replystill confused because I actually use separate power supplies(lipo battery) for each vd, after the isolator is installed I guess there will be no need for the second vd power supply right?

                Sure you could run both DACs, off one supply for VD. That's the simplest solution, and I think you will find it works quite well, and you will have one less power synchronization to worry about. :) Cheers! Russ Edited by user Monday, January 6, 2014 2:16:16 PM(UTC)
