Marking On ADC0804LCWM/NOPB

Hello,

This line shows the assembly information for the part.  The first two digits are the year and 6 week period that it was manufactured, the next four letters are the lot code of the wafer and the last three digits are the assembly site code.

The 49 means it was manufactured during the 9th 6 week period of 2014 (or if it is in equipment that was built before 2014 it would mean 2004).  The 55 means the 5th 6 week period of 2015 (or 2005).

Mike
