45.2 Features

The following are key features of the ADC:

  • Two Analog-to-Digital Converters (ADC): ADC0 and ADC1
  • 8-bit, 10-bit, or 12-bit resolution
  • Up to 1,000,000 samples per second (1 Msps)
  • Differential -ended and single-ended inputs
    • Up to 23 analog inputs per ADC (16 external channels)

      23 positive and 8 negative, including internal and external

  • Internal inputs:
    • Internal temperature sensor
    • Scaled core supply
    • Scaled I/O supply
    • Scaled VBAT supply
    • DAC0
  • Single, continuous, and sequencing options
  • Windowing monitor with selectable channel
  • Conversion range: Vref = [1.0V to VDDANA]
  • Built-in internal reference and external reference options
  • Event-triggered conversion for accurate timing (one event input)
  • Optional DMA transfer of conversion settings or result
  • Hardware gain and offset compensation
  • Averaging and oversampling with decimation to support up to 16-bit result
  • Selectable sampling time
  • Flexible Power or Throughput Rate Management

ADC0 can be configured to serve the Peripheral Touch Controller (PTC). Refer to the PTC chapter for additional information.
