Could you please give more details?

No, I’m using a custom board with the nRF9160-SIxA chip. I can read the ADC values, but they don't seem to accurately reflect the voltage level (in mV) that I want to measure.

Hi thwcs7,

What you are doing seems correct. What exactly happened when you say "I still cannot read ADC on pin P0.13"?

Are you working on the nRF9160 DK though? On the DK, P0.13 is connected to the external flash chip, so that might be why the reading is not correct.
