Hi Nordic Team,
I’m currently doing POC using the nRF54L15.
As part of the initial testing phase, I’m evaluating the "nrf/adc driver sequence sample" from the nRF Connect SDK using the nRF54L15-DK.
I’ve set up a basic test where I’m measuring ADC values using a potentiometer. The input voltage is supplied by the DK board’s VDD (1.8V).
In the device tree overlay file, I have configured ADC Channel 0 and assigned pin P1.11 for the measurement.

zephyr,input-positive = <NRF_SAADC_AIN4>; /* P1.11 */
zephyr,resolution = <12>;
};
};
However, I’ve noticed some unexpected behavior:
-
With the 12-bit ADC, I expect readings from 0 to 4095. Instead, the values range from 0 to 4092.
[ Note : at the 4092, its shows 1.8V multi-meter reading and other console mv reading also align properly with multi-meter reading.] -
Additionally, all ADC readings are even numbers—there are no odd values observed at all.
here I have attached the two log file : (i) adc_reading_2_9 (sdk version 2.9.1)0523.adc_reading_2_9.txt
(ii) adc_reading_3_0 (sdk version 3.0.0)

I observed the same behavior while testing the SAADC example as well. I followed the dev Academy nrfx SAADC example from the Nordic Developer Academy using the nrfx driver
and printed the ADC values for verification.
Could you please clarify, Is this nordic nrf54L15 hardware / chipset specified issue or some other Firmware / SDK specific issue ?
Looking forward to your insights.
Thanks & Regards,
Pratik Panchal
