There is no need for this.  The 30F3013 is nicely priced and comes with 12
bit A/Ds.  Designing the circuit so that all errors amount to less than 1
part in 8000 is the tricky part.  At that level you have to consider offset
voltages caused by currents thru ground paths and a bunch of other stuff.
This is certainly doable, but not something a newbie is likely to get right
the first time.
