https://devzone.nordicsemi.com/f/nordic-q-a/95019/false-steps-in-adc-measurementsHi, I am trying to measure a sensor once a second. I require to use oversampling to get 14bits of resolution to meet our target. We are observing a large step in values that are not consistent with the actual data. No change in temperature.

The offset calibration can switch between two codes if it&#39;s close to the&nbsp;limit between two calibration steps in the DAC.&nbsp;The accuracy of the calibration DAC is approximately 4 LSB12b, which means that in 14-bit mode the calibration step is approximately 16 LSB14b (differential mode, in In single ended it will be 2 x 16 LSB14b). I would consider this the most likely cause, but let me know otherwize.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
