Er� still confused. I don't see how increasing the sampling rate from 8-bit to 16-bit makes the sensor any more sensitive. When we're using terms such as "f-stop" we're just describing a mathematical relationship. Surely just because you can make the device more accurate in its description of what it's recording doesn't make it able to actually record more. I think someone else posted the example of a monitor displaying an image: whether it's displaying 16 colours, 256 colours, or millions of colours (the bit-depth) it's dynamic range (the difference between the blackest black and the whitest white it can display) doesn't change.
