Analog-to-Digital Converter
The Analog-to-Digital Converter (ADC) converts an analog input signal to its digital rep-
resentation. The features of this sigma-delta ADC include:
• 10-bit resolution
• Eight single-ended analog input sources are multiplexed with general-purpose I/O
ports
• Interrupt upon conversion complete
• Bandgap generated internal voltage reference generator with two selectable levels
• Factory offset and gain calibration
Architecture
Figure 19 displays the major functional blocks of the ADC. An analog multiplexer net-
work selects the ADC input from the available analog pins, ANA0 through ANA7.
