8.13 ADC

The 12-bit analog-to-digital converter (ADC) module in these devices, supports fast 12-bit conversions with single-ended inputs.

ADC features include:

  • 12-bit output resolution at 1.68Msps with greater than 11-bit ENOB
  • HW averaging enables 14-bit effective resolution at 100ksps
  • Up to 26 total external input channels
  • Internal channels for temperature sensing and supply monitoring
  • Software selectable reference:
    • Configurable internal shared reference voltage (VREF1) of 1.4V and 2.5V (requires decoupling capacitor on VREF+/- pins) to support 1.6Msps
    • Configurable internal only reference voltage (VREF2) of 1.4V and 2.5V to support 0.9Msps
    • MCU supply voltage (VDD)
    • External reference supplied to the ADC through the VREF+/- pins
  • Operates in RUN, SLEEP, and STOP modes
Table 8-8 shows the ADC channel mapping in the device.
