A/D 12 bit using PIC?

Hi

I know that the PIC's can do 10bit A/D. I was wondering if it is possible to use the PIC with no dedicated A/D chip to do 12bit or even 14bit A/D? and if "yes", can you please tell me how to do it?

I would like to sample at 2000 samples per second per channel, on 3 channels.

Thank you
Alex

There are PIC's with 12 bit A/D's. Try:
