[volt-nuts] Traveling Standards

[David C. Partridge]

May also be worth looking at AD584TH, though the tempco is poor at 15ppm/C worst case over [-55C, 125C], especially by comparison with LTZ1000 at 0.05ppm/C.  So I think you'd need to put it in a temp. controlled environment for predictability.

??? LM119A is a comparator not a V. ref. ???

Dear All,

Thank you so much for the great responses!  You have all given me a lot to think about.

Andreas mentioned the lm339.  One candidate I am considering is the lm119ah
