Interesting, the AD597 has disappeared from the Analog web page.
Pity, since the 595 doesn't seem to have the cheap package option -
it will run around $13 each.

Allied Electronics still have the AD597AR and I have the data sheet.
For a one off project, it would be a good choice.

No problem with the Type K in the exhaust.  It's what is used in EGT
probes.  You can buy a ready made EGT probe for < $30 if you look around.
