inputs table

This diagram shows which analog inputs are available for each Analog-to-Digital Converter (ADC) core.

  • ADC1 to ADC4 support up to eight analog inputs each; ADC5 supports up to 12 analog inputs.
  • These inputs include both external pins and internal signals.
  • Data channels select their analog input using configuration bits:
    • PINSEL[3:0] for positive inputs
    • NINSEL[1:0] for negative inputs
  • The ADC core uses the selected input and sampling time from each data channel to process the analog signal.
  • Refer to the product datasheet to identify the available analog inputs supported for each product package offered.
