    Hi wade,
    thank you for fast respond.

    how I can get new revision datasheet
    caused I need to attach that file to my summary job as documentation,

  • In reply to Fitra Neni Olya:

    I suspect this will take at least 2 and up to 6 weeks for the corrected datasheet to be on the web.

    Possibly you can reference this post for your documentation in the meantime.

    I will let the engineers working this know that sooner will be helpful.

    Regards,

    Wade
