https://devzone.nordicsemi.com/f/nordic-q-a/87185/sar-adc-is-giving-weird-measurementsHi, I am working with an nRF52832 in the nRF52-DK. I am trying to use the ADC with timers through PPI. I have a timer with five CC events, and one of them through ADC measurements. I think this is working fine.

The nRF52 DK has &quot;P0.03 (A0)&quot; next to&nbsp;one pin. I thought that was the AIN0 input of the ADC. It seems it isn&#39;t. Actually, P0.03 is AIN1, P0.04 is AIN2, and so on.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/364263?ContentTypeID=1Thu, 21 Apr 2022 13:39:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:adb4e1f8-1a24-4cb2-8982-06b893711cebdpalma<p><span>PIN_ASIC_OUTA is</span></p> <p><pre class="ui-code" data-mode="c_cpp">#define PIN_ASIC_OUTA NRF_SAADC_INPUT_AIN1</pre></p> <p></p> <p>Raw sample values when connecting the pin to VDD</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/Captura-de-Pantalla-2022_2D00_04_2D00_21-a-las-15.13.58.png" alt=" " /></p> <p><span>Raw sample values when connecting the pin to GND</span></p> <p><span><img height="487" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/Captura-de-Pantalla-2022_2D00_04_2D00_21-a-las-15.14.29.png" width="274" alt=" " /></span></p> <p><span>Thanks!</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/364219?ContentTypeID=1Thu, 21 Apr 2022 12:28:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7dfc2291-cf50-403a-a96f-3afa9065f523haakonsh<p>Can you share some of the raw sample values?&nbsp;<br /><br />What is the value of&nbsp;PIN_ASIC_OUTA?</p><div style="clear:both;"></div>
