LMC6082: LMC6082 Accuracy Drift over time

Christopher Loncaric

Part Number: LMC6082
Other Parts Discussed in Thread: LMC6084

Hello,

I am looking for long-term parametric drift data or HTOL (High-Temperature Operating Life) reports for the LMC6082 OpAmp.

Specifically, I need information on:

  1. Input Bias Current (IB) & Input Offset Current (IOS) lifetime drift

  2. Input Offset Voltage (VOS) long-term drift

  3. Channel-to-channel tracking: How well do the two channels within the same package match regarding VOS drift over time?
  4.  Open-Loop Gain (AOL) stability under long-term aging.

Any official reliability summaries or aging curves for the LMC608x family would be highly appreciated.

Thanks in advance!

Best regards,

Christopher

    Hi Christopher,

    You can find HTOL data for the LMC6082 in our Quality, Reliability and Packaging tool.

    Unfortunately, I'm unable to provide the specific long term parametric drift reports you're requesting, as this information is not something we have published for the LMC6082. 

    Best Regards,

    Hi Alex,

    Thank you for your reply.

    Since official reports are not published, could you check if any of the following is available internally. If necessary, also under NDA?

    • Raw/Internal Data: Delta-measurement logs from the LMC6082 qualification. Like Raw HTOL Test Data?

    • Family Data: Reliability reports for sister devices (e.g., LMC6084) or the same wafer process node that show parametric drift curves.

    • Alternative Tests: Long-Term Storage Life (HTSL) data tracking these parameters.

    Best regards,

    Christopher

    Hi Christopher,

    I apologize, but I'm unable to disclose that information.

    Although we do have long term drift plots for some of our devices (such as zero-drift amplifiers), the LMC6082 is not a device we have this data for. You can estimate the lifetime drift for 0 centered specs with a gaussian distribution (such as Vos and IB) using the distributions provided in the datasheet.

    You can find the full details on how to calculate long term drift specifications in this slide deck here. There is also a video associated with it, which can be found here.

    Let me know if you have further questions.

    Best Regards,

    Alex Curtis
