How to get proper footpring for ADA4937-2

How do I get the proper footprint for ADA4937-2 in Altium?

Very sadly, the datasheet does not state any footprint/soldering/landing pattern but merely the the package dimensions.

Also, a BXL file does not exist. So I downloaded the ADA4932-2YCPZ-R2.bxl which seems to be identical package, installed UltraLibrarian and got everything in Altium.

Eventually it created three components: CP_24_1, CP_24_1-L, CP_24_1-M.

All of these footprints are different, have weird dimensions and do not quite seem right. Even worse, I don't even know which one of them is the right one.

Due to lack of any information in the datasheet, I cannot even verify this information.

Thanks!

    Hi Eric,

    ADA4937-2 comes with a package option of CP-24-10 which is compliant to JEDEC Standars MO-220-WGGD-8. We apologize that there is no bxl file available in the product page. We will have it updated.

  • Hi Jino,

    Thank you for your response! That's very great! However - I still have a question on this footprint.

    I now found the ADN8810 which seems to have the same footprint (CP-24-10) and for which I found BXL files (ADN8810ACP.bxl and ADN8810ACPZ.bxl). After Altium import, I find three different footprints:

    1. CP_24_1
    2. CP_24_1-L
    3. CP_24_1-M

    They are all slightly different.

    Which one is the correct one?

    Thanks,

    Eric

    PS: I am confused: According to the ADN8810 datasheet/website the package must be CP-24-10 but the footprints are called CP_24_1. Is this OK?

    Hi Eric,

    I could not identify which is which among the 3 footprints is the correct one. I don't have the software in my PC and I can't check it myself. Would you be kind enough to attach screenshots of the footprints? Dimensions would be necessary.

    Regards,
