AD712 Zen chip

[Vince]

Does anyone know of a cheaper/better place to source these? I'd rather buy in bulk ish... say minimum of 20 or so

I still haven't found a cheaper and more realiable source for AD712's than allpartspipe2008. And gettin' these IC's at 1 euro / piece is a real bargain (about 5.25 euros / piece right now in Madrid, highly raised prices from past year that it was about a 4 euros / piece).

If you find a cheaper one, please share :)

It might be worth contacting some of these suppliers for direct pricing.

65 usd x 50 pcs, including shippin :)

Any reason to pay usd 135 for ​ 25 pieces?

As a joke, in not really fun :)

By the way, in Alibaba.com they list this ic as:

NEW AD712
Min. Order: 10 Pieces
FOB Price: US $0.01-1 / Piece

Really fun if I ad not lost half an hour of my time waiting for quotation :P

Give that a miss then!... I've been reading about the chip and the Zen and it sounds like it makes very little difference anyway, especially in low gain circuits... I've made one and tried 3 different IC's and I can't tell any difference so I think I'll just go with what I have.

I honestly feel a difference using AD712 in Zendrives compared to TL072 for example. Those chips are more expensive but that's a good price for them.
