We have P/N AD641AP with Date Codes 0043, 0045, 0313, and 0320. The Die (wafer) marking found on all devices is AD640 ADI  M  1988. The back side injector had PHILIPPINES with various numbers such as 04,07 etc. which varies but not unusual to see. If someone can confirm die markings to this P/N and also confirm that the markings 04, 07, 17 are not unusual that would help our inspection process.

thanks,

Don
