Other Parts Discussed in Thread: REF3325

The datasheet doesn't show LONG-TERM STABILITY for REF3325. Do we have such data?

Regards, Bernd 

  • Bernd,

    We do not have the Long Term Stability data for REF33xx to share with you BUT as part of the initial qualification all new products must pass a lifetest (an accelerated aging process in high temperature ovens) that requires maximum shift of the parameters like the initial accuracy to be no greater than the max/min spec shown in the PDS.  Therefore, in case of  REF33xx with the initial max spec of 0.15%, the maximum shift after 10 years is no greater than 0.15% or 1500ppm.

    For more details on the topic of long-term stability, please read my blog below:

  • Marek,
    thank you for the fast and comprehensive feedback.
