Overview of ADI Vref is here.

Be very careful about the "Out TC" value in the table though. It does not
necessary mean the worst case value and it may depend on the package.

We are using ADR03 and ADR43x series with 3ppm worst case
TC. For the ADR03, only the SOIC package and B grade
components offer the 3ppm worst case performance. The ADR43x
now has the MSOP8 option along with the SOIC8 option
which offers the 3ppm performance (B grade only).
