Hello!

I not found on datasheet information about AD5683R internal reference long term stability.

Interested about voltage deviations by day, month, year.

 

I need it to decide using internal reference or external like REF192.

 

REF192 datasheet have spec. for voltage drift of 1.2 mV for 1000hours.

 

What about AD5683R internal Reference?

 

What is the best reference with absolutely minimum voltage drift? (target = 1mV/Year max)
