Ok.

Don't laugh, but I am seriously a circuit goon. I have this thing that I
am building, and I am doing some funky stuff with voltages. I find I need
to be able to generate a differential voltage based on a pot. For example:

I have a 2.5V input to this circuit. When the pot is fully CCW (0) puts
out 2.5V on 2 separate lines, when it is fully CW (10) it puts out 2.2V
and 2.8V on 2 separate lines.

I am sure this is a fairly common circuit type, but to learn about it, it
would seem I need to know its name (all the schematics in the books are
listed by common name, not function). Could someone name that circuit?

Thanks
