5.1.3.1 ADC Feature Differences and Additions

AM261 uses the Type-4 ADC Post-Processing Block (PPB). This enables the following additional features compared to the AM263 Type-3 ADC PPB:

  • External Channel Selection – Two ADCxEXTMUX signals are provided for each ADC module. These can be used with an external analog MUX to control the channel select to route multiple analog signals to a single ADC channel.
  • Repeater Block – Enables fixed amounts of repeated conversions that can be used for oversampling, undersampling, phase delay, and sample spreads.
  • Oversampling - The hardware additions in the PPB that support averaging and min/max sample detection are available when oversampling. These can be used for applications like peak detection and outlier removal.
  • Synchronization – Sync inputs from either hardware or software allow for the PPBs on different ADC modules to be synchronized.
  • Global Software Trigger – This can be used to trigger multiple ADC SOC conversions with a single bit write from the CONTROLSS_GLOBAL_CTRL register.
