    Hi there!  Welcome to our e2e Forum!

    As per the original post, the ADS7800 marking is as follows:

          +-------------------+             \BB/ = BB LOGO                              
         !                          !              YM  = 2 DIGIT DATE CODE                    
         !       \BB/            !             LLLL = LOT TRACE CODE                       
         !                          !                S = ASSEMBLY SITE CODE                   
         !   ADS7800JU   !                                          
         !                          !                                                         
         !   YMLLLLS       !                                                         
         +--------------------+     

    The YM is Year / Month, so 77A603H is most likely 2017, July.  The number beginning with 91xxxx is 2019, January and 6Axxxx would be 2016, October (we use HEX values for the month).  The next four digits are the LTC and the final is the assembly site.  Are you having issues with any of these parts?
