726 (time to change the subject line (;->) )

I think the 726's temperature could be programmed by an external resistor.
Your conclusion must be right, of course, but the diagram you refer to might
be a typical courve for one chosen chip temperature.

I only have an uncomplete data sheet (2 pages), but it clearly shows
a temperature adjust pin. I'm almost sure that I have seen 726 circuits
with different resistor values, but I don't remember where.

Is there any additional information in the Fairchild book ?
