ADC Voltage Monitor[edit | edit source]

On MITO 8M Mini/Nano there is an Analog to Digital converter that could be used as a voltage monitor for the PMIC voltage rails.

It is connected to the AMUX output from PMIC. See PMIC PF8121 datasheet for more details.

The ADC component is a Texas Instruments ADS1114:

  • 16 bits resolution
  • Programmable Data Rate: 8 SPS to 860 SPS
  • Low Current Consumption: 150 µA (Continuous-Conversion Mode)

It is connected to the internal I2C1.
