Yes, LM399 good good! Me like! The dozen LM399 have now spent a day at an average 0.0uV deviation, +/-0.2u peak to peak probably below 0.1ppm rms (10s averaged), despite the room temperature changing by something like 5 degrees (C). Condition; Bench supply 12V, 12 IC paralleled, current limited by 2K7 to each IC, output via 2K7 from each.
I got my LM399 from ebay at $4.99 each. Seller polida2008. (I'm in no way associated with the seller). Buying ICs on Ebay is risky but these where good. _______________________________________________ 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.
