1998 Microchip Technology 1 M AN700 INTRODUCTION This application note describes how to implement anAnalog-to-Digital (A/D) Converter function Using amember of the PIC16C6XX series of these microcontrollers do not have a built-inA/D Converter like other controllers from Microchip, thecomparator function, internal voltage reference and tim-ers can be used to digitize an analog signal. Some of the standard PICmicros have a comparatormodule, consisting of two comparators, both of whichcan be connected to PORTA in a variety of configura-tions. The internal voltage reference divider can beused with the comparators to establish , one of the comparator inputs can be con-figured to the RA2 port allowing for the use of an exter-nal voltage reference.
