LTZ1000A Heater Temp

Hello.  I have been watching volt-nuts and time-nuts for a while now and I have a question.

I am considering designing a LTZ1000A based voltage reference.  I have noticed for more stability, some have lowered the heater temp of the LTZ1000 from 85C to 40C.

On the LTC1000A, Linear notes that the unit has a different die, and they recommend running the LTZ1000A 10 degrees higher than the plain LTZ1000.  Has anybody computed the values of the resistors to run the LTZ1000A at 50C ?

Thanks - Ben

Hello,

Theoretical value would be 12.4K.
Usually 12.5K are used for a LTZ1000A.

With best regards

Andreas
