https://devzone.nordicsemi.com/f/nordic-q-a/55090/saadc-analog-readingHi ... folks I am using nRF52832 and analog IR sensor , Working with the example saadc . In this case , i am giving the IR sensor input voltage as 5v , analog pin 2 .I am getting the voltage range above 500 to 850. can you explain me the calculationen-USTelligent Community 13Mon, 02 Dec 2019 14:47:18 GMThttps://devzone.nordicsemi.com/thread/223100?ContentTypeID=1Mon, 02 Dec 2019 14:47:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11c68179-2e00-4cbd-99d5-4a08fd24fa6bJared<p>Hi,</p> <p>You can&#39;t use the SAADC to sample a voltage that is higher than VDD. See the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/saadc.html?cp=4_2_0_36#saadc_frontpage">product specification</a> for information on how the SAADC works.</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
