A typo. It shouldn't have a minus sign, and 88dB is way way better than this tiny thing can possibly do.

That's what I think, too. I'm wondering if the "88" part is a typo, too. Still, a spec is a spec. If it's that good, we should see something great come of it, but CCD's alone don't make images. They've still got to get the image out of it intact and noise-free.
Here's to hoping Sharp's actually needs a 16 bit ADC for their new CCD! B)

Most definitely. They're off by a factor of hundreds. They would be doing well to get near 50dB. Have a look at a high end Kodak chip for comparision. The SNR and Linear Dynamic Range should be the same.
