I was just thinking along similar lines. Particularly the Cypress PSoC 5LP.
It has Delta-sigma ADC on board for which "nominal operation is 16 bits at
48 ksps". It also has Programmable Gain Amplifiers for which "the gain is
adjustable at runtime, including changing the gain of the PGA prior to each
ADC sample". And there's a "24-bit fixed-point digital filter
processor".
All on a neat little board with a snap off USB programmer and mini USB at
the other end for $10. Programming it is fairly straightforward thanks to
the free PSoC creator software, but that doesn't run on Linux unfortunately.

How about a Heath-Robinson solution?
Hook up an Arduino-mini (or the like) to voltage or digitally controlled
amplifiers and link it into the computer via USB. If that's not possible run an
external RS232 serial line to it.
Hi Thomas,
Sorry to dig up this oldish discussion and if I missed some of the ideas..
but it's actually quite interesting.
No problem - it's still not solved on our side, as the two solutions so far
were deemed too expensive for a test setup by my higher-ups.
