This application note describes a method for
implementing analog to digital (A/D) conversion on the
PIC16C5X series of microcontrollers. The converter
requires only five external components and is software
and hardware configurable for conversion resolutions
from 6-bits up to 10-bits and conversion times of 250ms
or longer. The method is usable for both voltage and
current conversion and uses a software calibration
technique that compensates for time and temperature
drift as well as component errors. PIC16C5X microcontrollers
are ideal for simple analog applications
because:
