Hi David, do you have a link to the circuit using the LM389 please, I'd like to see how it's used.

Thanks, Don Black.

I remember one clever log/antilog amplifier that used the National
LM389 to implement the above temperature regulation scheme. It was
amazingly cost effective since no temperature compensation was needed.
I would still be using it if the LM389 was not discontinued.
