Digital potentiometer - determination of resistor aging

Hi Frank,

Unfortunately, this is an old part and retrieving the drift data would be difficult. I have an HTOL (high temperature operating life) data though, which resulted to a pass. The part operated in a 125C to 135C temp for 500 hours.

Hello Yokki,

thanks your your reply. What was the pass/fail criteria, you applied for the HTOL test? (which electrical parameter were evaluated?)

Best regards
Frank

Hi Frank,

The specification for the HTOL test was JESD22-A108. Hope this answers your question!

Yokki

Hello Yokki,

just to get your answer right: The HTOL test according to JESD22-A108 was focused to check, if non-volatile configuration of digital poti remained unchaged during stress test diration. Verification of other electrical parameters was out of scope. Do you confirm?

Best regards
Frank

Hi Frank,

After performing HTOL, units are subjected to full functionality electrical test. Thank you!

Dear Yokki,

is the mentioned HTOL test report available for public access. Found only these quality reports
ADI_PCN_21_0035_Rev_-_Qualification Results Summary for TSSOP_4.4 at AP1.pdf
ADI_PCN_11_0218_Rev_B_Qual Results_TSSOP[1].pdf
which doesn't include HTOL test case.

Best regards
Frank
