Okay, here's my dream chip-I would buy a lot of these. High channel count AD converter (32+ inputs). This device should be capable of sampling high-quality audio, so sampling rate will be a function of number of input channels. Would require fast, accurate muxes (or 32+ ADCs!)
* Programmable gain on each channel.
* Porgrammable Unipolar/bipolar input.
* Parallel output (or very high speed serial--LVDS maybe)
* Progammable sampling sequence
Good luck. Let me know when you need a beta tester!
