I can’t find the maximum junction temerature of AD797 in its datasheet. What is
the value?

 

The max junction temperature is 150°C, same as other parts on the same process.

By the way, the AD797 came out in 1992 and is on a very old process.  The
AD8597 came out in 2008.
It is on a much newer process, lower supply current, has a max voltage noise
that is lower than the max
on the AD797.  The AD797 is being used by hundreds of companies successfully in
production, but
because of the high bandwidth of the output stage is difficult to use.  It
requires a very clean pc board
layout, and two bypass caps very close to each supply pin.  The AD8597 is much
less touchy.
