Hello,
I am looking for suggestions for a good reliable general purpose
voltage reference chip. The voltage I need eventually is 2.5 V, but I
could divide down from 4.096 or the like. The system has a 5V supply.
I don't need anything too accurate, +-.01V would be good. If possible,
I'd like something that has been around a while so that I can hope
that it will be available for 10-20 years, or at least a pin
compatible replacement. Is there a standard voltage reference pinout?
Temperature stability is also important, but I'm not sure exactly how
much so. Is 100 ppm/deg C unreasonable?
Thanks for any advice,
Glenn
