Does the same restriction apply for the LPCOMP?en-USTelligent Community 13Thu, 12 May 2016 11:18:40 GMThttps://devzone.nordicsemi.com/thread/52186?ContentTypeID=1Thu, 12 May 2016 11:18:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6ba80f93-6286-478a-890f-4ad510b3feb7Stefan Birnir Sverrisson<p>Hi Nick</p> <p>The internal impedance of the LPCOMP is extremely high, so a connected external circuit with high impedance should have no effect on the output of the LPCOMP, or very close to no effect.</p><div style="clear:both;"></div>
