The transformer I use has 4 pins.

paulb · 11th February 2009, 02:42 PM

Only 4 of the replacement are used; the other 2 could be cut off. If it physically fits on the PCB it should work. It looks like the pins are at the right spacing.
Note DigiKey is out of stock on the original.

Crap! I didn't realize that. I hope we can find an alternate source.

in the past I made mine out of toroid ferrite rings and 3-5 turns of wire, so it can be intermediate solution but an alternative would be better solution.

I am no expert on these, how about this one from mouser

Murrata DA101C

There is also from Murrata DA102 and DA103C but I do not know which one would be more suitable, on the first glance pinout is ok, but with my daughter on my back is hard to type

I e-mailed Newava to ask them about this.

I forgot to mention that I had started a forum a while back specifically for the ezDAC/ezDual projects. Anyone is welcome to join. It might be helpful for future discussions of the project.

Good news on the clock front. It seems Mouser still has these in stock (but I'd suggest buying them ASAP):

Before we all go off and individually buy parts... Has anyone considered doing a group buy for the (majority of) parts? This would save everyone a lot of money (at least that's what experience tells me). Now, the usual rule is that whoever proposes this question just volunteered themselves... I will not follow that rule. I just did a group buy for the revC design. So I will take a break. But if anyone wants to take the lead I would be happy to provide counsel and advice based on my fresh experience.
