Hello

first I want to ask if it makes sense to use dual 3.3V supply for digital Eh? (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 reply
still 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!
