You take the wrong chip, you put it on a one or two layer board, you do not separate the grounds, you do not ..... you do ...
and then you post "how do I code it to be precise and constant" That is NOT a software matter. see http://www.8052.com/faqs.phtml?FAQ=128848 AGAIN! and get a dose of reality. Once you have the analog circuitry stable; non-drifring; done with a suitable chip; well shielded, with a solid, separate analog ground plane on a 4 or 6 layer board; well isolated from power supply noise and hum; well isolated from the digital noise from the digital circuitry, then MAYBE, just MAYBE you have a chance to talk about 15 bits.
