Are you using any SDK example as base?</P> <P lang="es-419">How is the board being powered, and how are you measuring/verifying the supply voltage? Could you confirm that the ADC pins are correctly configured and routed?</P> <P lang="es-419">&nbsp;</P> <P lang="es-419">To verify the reference configuration, could you please measure the VREF_OUT voltage while the ADC is running and confirm if approximately 2.0 V is being sourced?</P> <P lang="es-419">&nbsp;</P> <P lang="es-419">Best Regards,<BR />Ana Sofia.</P> Thu, 22 Jan 2026 19:02:46 GMT https://community.nxp.com/t5/MCX-Microcontrollers/MCXW71-ADC0-Reading-Pins/m-p/2298549#M4709 sofiaurueta 2026-01-22T19:02:46Z
