X3-SD A/D absolute maximum rating for differential voltage

[pitaro]

I understand from the user manual that the absolute maximum rating on the input pins is +/- 12V with respect to GND. I am guessing that exceeding these limits will cause damage to the A/D or input buffer circuitry.

I also understand that the differential voltage is supposed to be between +/- 10V (Vin+ minus Vin-).

Is it safe to assume that as long as the Vin absolute maximum ratings are not exceeded with respect to GND, the A/D will simply saturate and no damage will result if the magnitude of the differential voltage is between 10V and 24V?

If not, this leads to two questions which affect my pre-amp design.

1. If I exceed a +/- 10V differential, does the A/D simply saturate or is it or the input buffer circuitry damaged?
2. If the A/D simply saturates, what is the absolute maximum rating for the differential voltage?

See responses below. Attached is an input channel schematic to help with your understanding. The amp is TI OPA1632.
