ADC pin max voltage tolerance

Hi, I’m using a Colibri iMX7D module and I have an analog temperature sensor connected to one of the ADC pins of this SOM. Is this pin 3.3V tolerant? I known that the Vref of the ADC is 1.8V, so this would be the max voltage able to measure, but what are the risks of putting on this pin more voltage?, could it damage the SOM?


Hi @franco_6996,

The max voltage for ADC is 1.8V, as stated in section 5.20 of the datasheet:

If you raise the voltage, you can damage your module permanently.

Best Regards,
