Analog-to-Digital Converter
Architecture
PS019921-0308
The Analog-to-Digital Converter (ADC) converts an analog input signal to a 10-bit binary
number. The features of the sigma-delta ADC include:

voltage reference generator) of the ADC. The ADC converts an analog input signal to its
digital representation. The 12-input analog multiplexer selects one of the 12 analog input
sources. The ADC requires an input reference voltage for the conversion. The voltage
reference for the conversion may be input through the external VREF pin or generated
internally by the voltage reference generator.
12 analog input sources are multiplexed with general-purpose I/O ports
