The ADM8316/18/19/20/21/22 are automotive qualified versions of the ADM6316-22
parts. They are pin-for-pin compatible but not spec-for-spec as this was a full
chip re-design. In general, the specs are the same or better on the new
automotive part so in almost all cases these parts could be used as a drop-in
replacement for the ADM6316-22.
