Description | 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 1... |
Features |
ious 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 value. This mapping function is defined as the transfer function. An ideal transfer is one in which there... |
