https://devzone.nordicsemi.com/f/nordic-q-a/2851/external-reference-impedanceI am planning to use the LPCOMP in conjunction with an external reference. I would like to just use a voltage divider to create the external reference. Are there any impedance requirements for the external reference?en-USTelligent Community 13Fri, 20 Jun 2014 06:46:50 GMThttps://devzone.nordicsemi.com/thread/10869?ContentTypeID=1Fri, 20 Jun 2014 06:46:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11bfd45e-314c-4848-aebc-6a871fe03b04Stefan Birnir Sverrisson<p>Hi Lucas</p> <p>Having high impedance instead of low impedance voltage source for the LPCOMP external reference will not have any noticable effect on the output of the LPCOMP</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10868?ContentTypeID=1Thu, 19 Jun 2014 18:04:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fe87a275-7ec4-4407-8daa-873bb7b5258dLucas<p>By external reference I am referring to AREF1/0</p><div style="clear:both;"></div>
