LM399 with external oven

<< < (5/5)


--- Quote from: Kleinstein on June 07, 2023, 09:34:09 am ---AFAIK the datron 1071 has a LM399 or similar reference. So it would be a comparison of two comparable references only.

I'm pretty sure it has one or two selected 1N82x temperature compensated zeners. I'm not aware of a Datron instrument using LM399, just temperature compensated zeners or LTZ1000.

So it might be a bit better than the LM399 in noise and drift.
