Chapter 9 Analog-to-Digital Converter (S08ADC10V1)
9.6
This section contains information for using the ADC module in applications. The ADC has been designed
for integration into a microcontroller used in embedded control applications requiring an A/D converter.
9.6.1
The following sections discuss the external pins associated with the ADC module and how they should be
used for best results.
9.6.1.1
The ADC module has analog power and ground supplies (V
