Using the Analog-to-Digital Converter of the 8XC552 Microcontroller


The 80C552 microcontroller has an on-chip ADC. The converter consists of an 8 input analog multiplexer, and a 10bit binary successive approximation ADC. To obtain the 10bit accuracy, it is important to pay attention to the design of the application. First, the operation of the ADC is described. Then, design and layout subjects are described that can influence the accuracy of the conversion result.
