https://devzone.nordicsemi.com/f/nordic-q-a/48152/using-saadc-to-determine-parameters-of-a-voltage-deviderHello I am using nrf52840 and am trying to determine the parameters of a voltage divider using the SAADC. Vin is the VDD voltage of the chip, R1 is 4640 ohms and R2 is 38600 ohms (measured by using a multimeter). I have attached the Vout voltage toen-USTelligent Community 13Thu, 27 Jun 2019 13:37:26 GMThttps://devzone.nordicsemi.com/thread/195174?ContentTypeID=1Thu, 27 Jun 2019 13:37:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a68238a7-f572-46e2-94c5-9bf13caaa976awneil[quote userid="79948" url="~/f/nordic-q-a/48152/using-saadc-to-determine-parameters-of-a-voltage-devider/195163"]That worked[/quote] <p>Please verify the answer:</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/3583._5F00_Verify_2D00_answer_2D00_nordic.png" /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/195163?ContentTypeID=1Thu, 27 Jun 2019 13:21:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f9d9209d-bd7d-4841-92fc-4ae5911acecdJohnnyMcMan<p>Thank you haakonsh.
