Here is a high-level overview of the 12-bit, 40 Msps Analog-to-Digital Converter (ADC) in the dsPIC33A MCU with the data channels highlighted:

system diagram

  • A data channel is a group of configuration settings that control the conversion process for a specific analog input, including:
    • Analog signal pin
    • Sampling time
    • Conversion mode
    • Trigger source
    • etc.
  • Each ADC can support up to 16 data channels (see device data sheet for details).
  • All data channel settings are configured in the ADnCHxCON1 register.
  • Data channels within each ADC are processed based on their natural priority.
Information

Note: On these pages (and datasheet), the terms conversion channel, data channel, and channel all refer to the same concept and are used interchangeably.
