I need already the AD1865N-K, digikey only sell 15, therefor itīs good to make a group buy, perhaps together with other chips.
Many people just asked if itīspossible to buy at Ebay, and it seems one seller is good, but nobody stays without doubt and the most bought in group buy on Digikey, the only official source I know.

Started from the first item: 470 ohm and 680 ohm resistors are "non-stock" in Mouser, minimum order is 5000. Couldn't find them in DigiKey. Did I miss anything?

I am new.

I can sell all resistors for this DAC!

Quanghao, the circuit for SSHV posted above lists for D5 & D6 - 1N4142A but the BOM (on page 179 of the original thread) says 1n4172?

I suspect the part we want here is 1N4742 or 1N4742A a 1W 12V Zener Diode....

Is this correct and if it is could you please make the corrections to the circuit so others don't have a problem.

Thanks!

Hi! Im sorry
that is I m wrong, 1n4142 is correct!
1n4742 and 1n4742 is one, this is zenner diode 12V

My be not need this Diode, if you can not fine it , you can change Zenner diode from 6.8V to 15V, 1/2W.
SSHV many time not need this diode, but It is still very excellent!
