ADC appears inaccurate on old date code partshttps://devzone.nordicsemi.com/f/nordic-q-a/118399/adc-appears-inaccurate-on-old-date-code-partsWe have a design in production using the NRF52833 -QIAAA0, Datecode 224700 and later in the hundreds. Recently the assembler supplied NRF52833 -QIAAA0, Datecode 2126DS. The ADC which was calibrated and accurate on DC224700, and now on DC2126DS isen-USTelligent Community 13Tue, 28 Jan 2025 15:17:17 GMTRE: ADC appears inaccurate on old date code partshttps://devzone.nordicsemi.com/thread/520408?ContentTypeID=1Tue, 28 Jan 2025 15:17:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:130f9a7c-0d54-4104-bc64-6054a79978abKenneth<p>Hello,</p> <p>I am not aware of any changes no, but if there were they should be part of a product change notice:<br /><a href="https://docs.nordicsemi.com/category/nrf52833-category">https://docs.nordicsemi.com/category/nrf52833-category</a>&nbsp;</p> <p>I guess the first question is whether you are running the calibration procedure of the ADC every time before sampling?<br /><a href="https://docs.nordicsemi.com/bundle/ps_nrf52833/page/saadc.html#ariaid-title15">https://docs.nordicsemi.com/bundle/ps_nrf52833/page/saadc.html#ariaid-title15</a>&nbsp;</p> <p>Also, can you share what change you are measuring?</p> <p>Kenneth</p><div style="clear:both;"></div>
