What cheap walwart is needed to power the ezDual ?

Thanks,
JG

I think I have a 12VAC, 1A walwart powering mine. Either 12 or 15, I'll look it up when I get home. What voltage will your regulators be set at?

Hmm, not sure yet. What voltage would you suggest?

Just another quick question... Is the ezDac single sided? (are there only components on the top side?)

The ezDAC is double-sided, but there are only a handful of components on the bottom.

Evan,

Just curious, why the low value for the I/V resistors and such a high gain in the op-amp?

The theory is that it should have less noise and be more linear. At least, that's what I remember reading.

Thanks Evan,

I was just wondering because I have seen the opposite a few times (high I/V R with low gain op-amp).

Two questions before ordering parts.

1 - For T on ezDAC will PE-65612 do the job ?
Specs here : http://www.alldatasheet.com/datashee.../PE-65612.html

The PCB shows a 4 pins footprint.
All the refs quoted in the Bom's are 6 legged...
What is the orientation of the legs when ezDAC is shown on the bottom, rounded side on the outside for T ?

Do you have a Mouser ref part for this ?

2 - F1/F2 fuse on ezDual : can they be omitted ?
Those parts are hard to find and very expensive...
Bypass and have fast blow fuses behind the tranformer ?

Thanks for your advised answers !

F1 and F2 can be ommited, I did you just have to jumper it instead.

I was just wondering about this tip for the fuses, you confirm.

One question remaining, does a PE-65612 is ok as T on ezDAC ?
Specs : http://www.alldatasheet.com/datashe...E/PE-65612.html

The PCB shows 4 pins footprint, refs in Bom's have 6 legs.

Last part before closing my order sheet.
