I know and use FPGAs quite a lot between my microcontroller and external interfaces and learned to value the flexibility of this setup.

Now I am wondering whether such a thing exists for the analogue world, too: an array of opamps, filters and comparators together with routing interconnect in a single package.

I've found a sparse selection of programmable gain amplifiers and some programmable higher-order filters at mouser and digikey but nothing with an programmable interconnect.

Does such thing exists? Or are we stuck with special made analogue interface circuitry?

Yes, it's called (originally enough) a Field Programmable Analog Array. See http://en.wikipedia.org/wiki/Field-programmable_analog_array It was introduced about 20 years ago, and never really caught on.
