LMV881: Device mark difference of LMV881

Hi, Dave!

Thanks for reaching out.

In short, these two LMV881LEE/NOPB labels are in fact the same. The codes simply signify that they are from different lots.

For example, when looking at the device with a top mark of '19C':

The 19 signifies the "year/month date code" (1 = 2021, 9 = September).

The C signifies the last alphabetical digit in the lot code (C = last letter in assembly lot code, as shown on package label).

The same logic applies to the device with the lot code '15E.'

I hope this helps!

Best regards,

Alex Soudah
