Part Number: LMP7704

Hi,

I would like to know if the same die is used for both the LMP7704 and the LMP7704-SP.

    Hi Mikayla, 

    The LMP7704-SP appears to be based on the same underlying die used in the LMP7704, but even if they share an identical die, the production flow of space grade devices is very different compared to the commercial grade versions. For more details, see the TI Space Products Guide. In the same vein, there are also differences between the engineering evaluation model of the LMP7704-SP and the fully qualified version:

    Paul Grohe said:
    TI engineering evaluation (/EM and -MPR) models are units intended for engineering evaluation only. While using the same die as fully qualified and processed space-grade products (QMLV or products appended with the suffix -MLS), they are processed to a noncompliant flow (for example, no burn-in) and tested to a temperature rating of +25°C only. These units are not suitable for qualification, production, radiation testing or flight use. Engineering models are not specified for performance over the full military specified temperature range of –55°C to +125°C or for operating life. For more information about engineering models, see the “TI Engineering Evaluation Units vs. MIL-PRF-38535 QML Class V Processing application report.

    Let me know if you have any questions.

    Best Regards,

    Alex Curtis
