https://devzone.nordicsemi.com/f/nordic-q-a/94845/how-to-get-maximum-saadc-precisionFor measuring (lithium -&gt; VDDH) battery voltage, I am looking into how to get the best precision out of the built in SAADC of the nRF52840 and how to quantify that. By reading through the documentation and the forums I have gathered the following: en-USTelligent Community 13Thu, 15 Dec 2022 15:19:10 GMThttps://devzone.nordicsemi.com/thread/400903?ContentTypeID=1Thu, 15 Dec 2022 15:19:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:996f11cd-45a8-4de1-8cce-a337b2001cb8Priyanka<p>Hi Tobias,</p> <p>Yes, the EG is Error of Gain, but the INL does not include the EGs. They are just two of the other different errors which contribute to the total absolute error.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/400502?ContentTypeID=1Wed, 14 Dec 2022 04:47:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f8b3ba4d-12ab-4d13-a73f-99f52abe2bfdPeace Makes Plenty<p>Take a look at this application note from Analog Devices:&nbsp;The ABCs of Analog to Digital Converters: How ADC Errors Affect System Performance.
