Thanks for all the help and suggestions folks......
I am just too nervous to buy from a non authorised dealer.....who knows what I'd get if I did get anything. Yes it's for production.
Also not happy at using the non-A 2ppm version, the selling point of my voltage sources is partly the stability and I advertise it with the AH version.....and it would play on my mind too much.
Guess I just wait for stock.
Frustrating thing is I just bought 25 from Digikey just a few weeks ago......if only I'd known.
PS. I have a begging email in with Analog Devices Inc......surely they have some in a drawer somewhere.....
Ian.
