Peripheral ADC[edit | edit source]

Description[edit | edit source]

The ADC interface available on ETRA SoM is based on STM32MP1 SoC.

The ADC port supports the following standards and features:

  • up to 2x ADCs which can operate in dual mode
  • 16, 14, 12, 10 or 8-bit configurable resolution
  • ADC conversion time is independent from the AHB bus clock frequency
  • can manage Single-ended or differential inputs
  • self-calibration (both offset and linearity)
  • up to 6 fast channels
  • up to 14 slow channels
  • speed adaptive low-power mode to reduce ADC consumption when operating at low frequency
  • 3 analog watchdogs per ADC
  • ADC input range from DGND to VDD
