https://devzone.nordicsemi.com/f/nordic-q-a/73585/saadc-noise-in-analog-pin-and-digital-data-of-nrf52832Hi, I am using a custom board to record 2 channels of data in differential mode, convert them to digital by AIN4,5 and saadc in nRF52832, and then transmit the converted data with ESB_ptx. when I imply an input to the analog front end or even if I shorten-USTelligent Community 13Tue, 06 Apr 2021 08:25:42 GMThttps://devzone.nordicsemi.com/thread/303032?ContentTypeID=1Tue, 06 Apr 2021 08:25:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a7d8d24-0063-4933-abb5-4fc373f234b6haakonsh<p>Is this measured on the DK or a custom board?<br /><br />What&#39;s the magnitude of the noise?&nbsp;<br /><br />I suggest you enable the HFXO when sampling, and if possible, not use the RADIO while the SAADC is sampling.&nbsp;</p><div style="clear:both;"></div>
