Does this comparator exist....

Has the usual two inputs, inverting and non-inverting, BUT it switches
when the DIFFERENCE between the two inputs is some reference value,
either fixed/built-in, or adjustable by an extra pin?

I know I could construct such a thing, but I'm looking for something
small, minimum pins, etc., i.e. a Joerg part ;-)

How about a TL431?

If you want something faster, there's the MCP65R41T.

Lots of LVDS-to-CMOS receivers have some built-in offset, ca 100 mV. All the
ones that we've tested behave like good r-r comparators. Cheap and fast.
