We are looking at old vintage part AD790 and wondering how is maximum junction and package temperature. It's datasheet only says "temperature" but assuming it is "Ambient temperature", please correct me if I'm wrong, but no description about junction or package.
If you provide any definition of maximum operational junction temperature and, maximum operational package temperature, it would be very much appreciated.
The problem is finding a new part that runs on +/-15V and is in a PDIP; there aren't any.
Look at the AD8469, AD8468, ADCMP609 or ADCMP608. You can get little adaptor boards
from sparkfun.com and solder SOICs on it and plug it in a DIP socket.
