Using the Analog to Digital Converter

M Authors: www.DataSheet4U.com AN546 Note that the digital output value is 00h for the analog input voltage range of 0 to 1LSb. In some converters, the first transition point is at 0.5LSb and not at 1LSb as shown in Figure 2. Either way, by knowing the transfer function the user can appropriately interpret the data. Using the Analog-to-Digital (A/D) Converter Sumit Mitra, Stan D’Souza, and Russ Cooper Microchip Technology Inc. Transition Point The analog input voltage at which the digital output switches from one code to the next is called the “Transition Point.” The transition point is typically not a single threshold, but rather a small region of uncertainty (Figure 3). The transition point is therefore defined as the statistical average of many conversions. Stated differently, it is the voltage input at which the uncertainty of the conversion is 50%. INTRODUCTION 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 (VREF) • Configuring the RA3:RA0 pins Code Width The distance (voltage differential) between two transition points is called the “Code Width.” Ideally the Code Width should be 1LSb (Figure 1). COMMONLY USED A/D TERMINOLOGY The Ideal Transfer Function In an A/D converter, an analog voltage is mapped into an N-bit digital valu.
