https://devzone.nordicsemi.com/f/nordic-q-a/20584/ai-and-prescaling---impact-on-precisionHello all, I&#39;m currently modifying my Analog Input circuit schematics to improve precision. I&#39;m adding after my voltage divider, an opamp as a voltage follower to ensure precise measurement. (as you might have understood, power/consumption isn&#39;ten-USTelligent Community 13Wed, 22 Mar 2017 18:03:41 GMThttps://devzone.nordicsemi.com/thread/80234?ContentTypeID=1Wed, 22 Mar 2017 18:03:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:386d753a-9e6e-497d-ba48-cf2bba1ac33fFrancois<p>Thanks! I went for that :-). We will see!</p> <p>Have a nice evening.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/80233?ContentTypeID=1Wed, 22 Mar 2017 13:31:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bea0d291-65e5-465a-9f89-af88d7722d16J&#248;rgen Holmefjord<p>Hi,</p> <p>There is no difference with regards to precision on the two scenarios you propose. The 1.2V input range will give you a bit lower input resistance.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
