AFE4300: Batch number

Tool/software:

I would like to know what kind of information I can extract from the AFE4300 Batch number, i.e. 

1. 29AX87WG4
2. 26C13PWG4
3. 22CDVQWG4

The n° 2 seems to have a different behavior from the standard one during the internal calibration procedure. 

Thanks in advance
