Hi Ralf,

TI doesn't disclose detailed information about the product marking because it provides counterfeiters exactly what they need to mark counterfeit IC products. The e2e link suggested by Kai provides the basic marking format so you can find from the first two digits the year and month that the particular device was produced.

If you obtained the OPA227U devices directly from TI, or an authorized TI distributor it should have valid date and lot codes.
