When was the EOL letter for the OPA2604AU issued?

The dual package of OPA604 may have been obsolete for several years now. The part was discontinued and obsolete for at least 5 years now, may be as early as 2015, see the previous E2E thread.

However, the OPA604 singlet is still available, see the TI  E-store.
