I have been off the list for a while, but noticed that there where some posts on the LTZ1000 and LM399 about a month ago.
I just have a comment; the requirements on these two references (standard datasheet implementations) are very much opposites: - LTZ1000 requires very stable resistors but is practically immune to supply voltage variations. - LM399 does not require high stability resistors but requirements on stable supply voltage are high. On the $ of one LTZ1000 board, you can get a number of LM399 paralelled & averaged. But one LTZ1000 runs on less power than one LM399 my 2c _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
