I need a series of led's (about 7) to use as a voltage reference. I
want to use led's because I need a certain tempco and using a series of
led's for the voltage reference will give me the right tempco. Ideally
I'd like a part that I can get cheap (naturally), maybe from one of the
surplus houses like allelectronics, goldmine or bgmicro. But I haven't
found anything from them, so I might have to go to a regular supply
house. I used digikey's excellent web site to search for diodes in
series or array but didn't get anywhere.
To make the prototype I soldered led's in series by hand, but I may end
up making a bunch more of these for friends and I'd like to find a part
that has led's (or for a distant second choice, ordinary silicon
diodes) in series, or perhaps array. For reasons that I don't want to
go into here, I won't use a single led and divide the voltage up
resistively.
Any info on availability of a part like this? Nothing fancy, just a
bunch of led's in series, and the smaller the better.
