PIC18F14K22LIN
5.0 ANALOG-TO-DIGITAL
CONVERTER (ADC) MODULE
The Analog-to-Digital Converter (ADC) allows conver-
sion of an analog input signal to a 10-bit binary repre-
sentation of that signal. It functions the same as
described in the “PIC18F1XK22/LF1XK22 Data Sheet”
(DS41365) with the following differences.
