Long-Term Stability of OPA2376-Q1

Other Parts Discussed in Thread: OPA2376-Q1, OPA2376


Dear, All

The customer is considering the OPA2376-Q1.
They are focused on Long-Term Stability.
However, the data sheet of OPA2376-Q1 is not listed is Long-Term Stability.
Please provide if there is data in the following Long-Term Stability.
- Input offset voltage
- Input voltage noise
I'm happy, if there is a same data as FIG. 22-24 of REF50xx-Q1's data sheet.

Thanks, Masami M.

  • Masami,

  • Masami,

    As part of the product qualification process, OPA2376-Q1 was life-tested for the equivalent 10-year operation at room temperature and it passed the maximum allowable Vos shift limit of +/-25uV (5-sigma); what this means is that the typical part with the initial Vos =5uV (1-sigma) may typically shift after 10 years of constant operation at room temperature by +/-5uV, thus ending up at either 0uV or 10uV (5uV+/-5uV).

    Since the broadband noise is inversely proportional to the current biasing the input differential pair, as the current may change by up to +/-10% over ten-year life of the product at room temperature so may the broadband noise.

    It is important for you to know that OPA2376 typical broadband noise spectral density specified at 7nV/rt-Hz, may vary due to normal process variation by +/-20% while low frequency, 1/f, noise may vary by as much 2x; these numbers do NOT apply to a long-term shift but only lot-to-lot variation in noise figures from their typical initial values.


  • Hi, Marek-san,

    Thank you for your reply.
    I'll answer to a customer.
