Later the boss didn't want to have an outsider involved so I didn't proceed. I saw this XTR thingie in there and urged them to design it out, prontissimo. But found them 1k of them in Italy (not DFN) as a courtesy, which they probably slurped up because they had some boards already made. The usual distributors were non-stock. >> Suggest to move to another 4-20mA transceiver but I guess for your >> client it's too late.

Sure there isn't any other way to do this board? Otherwise you guys probably have to put in orders for oodles of these, wait until end of April, and then stash them all in a safe deposit box. > >>> In deep need of those devices and, despite warnings, he finally >>> turned to Chinese brookers... and got burned. >>> He bought 500 of what revealed to be faked ICs (why they do bother >>> with $1 devices on that small market is beyond me). >>> The boards were stuffed with that POS, but fortunately he only >>> launched 50 of them. >>> >>> >>> Now, I did manage to find 15 pieces, yes!, but I suspect it's all over. >>> >>> Now, before he turns again in despair to another of those bastards, I >>> thought I might ask if some here is using it and could sell(or >>> whatever), say fifteen to one hundred of those, which will get him >>> out of trouble (lots of sample enquiries on a ramping up cute little >>> new product). >>> >>> He's willing to pay a fair price for them... >>> >> >> Farnell Asia says "awaiting delivery", whatever that means.

Pretty sad state of affairs when semi mfgs announce nice parts and then can't deliver. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
