This application note is intended for PIC16C7X users with some degree of familiarity with analog system design. The various sections discuss the following topics: • Commonly used A/D terminology • How to configure and use the PIC16C71 A/D • Various ways to generate external reference voltage (V REF ) • Configuring the RA3:RA0 pinsM Using the Analog-to-Digital (A/D) Converter AN546 Note that the digital output value is 00h for the analog Authors: Sumit Mitra, input voltage range of 0 to 1LSb. In some converters, Stan D’Souza, and the rst transition point is at 0.5LSb and not at 1LSb as Russ Cooper shown in Figure 2. Either way, by knowing the transfer ……
