Don't know about the ATIK2C, but for a given chip design, well depth
tends
to scale with pixel area which would make it about 45k electrons? but you
could try asking on

BTW , given its 8 bit webcam heritage, I would guess that the ATIK would
saturate the A/D converter long before full well depth is reached.
