Over consumption on the SAAChttps://devzone.nordicsemi.com/f/nordic-q-a/47298/over-consumption-on-the-saacHi, I use the SAADC with the NRF52832. This is the schematic used : When we use AN_IN (TOR_IN 1 and TOR_IN 2 are not used), only the components assigned to AN_IN are mounted on the board. The consumption increase when we put a voltage on T20 en-USTelligent Community 13Fri, 17 May 2019 06:58:01 GMTRE: Over consumption on the SAAChttps://devzone.nordicsemi.com/thread/187626?ContentTypeID=1Fri, 17 May 2019 06:58:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1ab6b0c7-9122-4058-8ed1-4712ba8edd4eMehdi GHARBI<p>We found the problem. The pin P0.03 is floating so when i apply a potential, the GPIO is in state unknown and the consomption increases. Now the pin is like Analog input =&gt; see pin configuration below :<img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1558076202025v1.png" alt=" " /></p><div style="clear:both;"></div>RE: Over consumption on the SAAChttps://devzone.nordicsemi.com/thread/187526?ContentTypeID=1Thu, 16 May 2019 11:58:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c6e8e685-0fda-4e5b-8c92-9d84f936e7e1Stian R&#248;ed Hafskjold<p>Can you try to cut the trace close to P0.03 and supply voltage to the pin directly? It&#39;s not clear to me if the current is flowing into the chip or through any of the external components.</p> <p>Can you please post the complete ADC initialization code? Thanks</p> <p>Can you also try to init the ADC to use another pin, and supply voltage to this pin? I&#39;ve seen similar excessive current that increases with voltage if the ESD diodes on the GPIO are damaged.</p><div style="clear:both;"></div>RE: Over consumption on the SAAChttps://devzone.nordicsemi.com/thread/187143?ContentTypeID=1Wed, 15 May 2019 07:41:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0cc2b738-8ebe-4ac0-81d8-f2418cd32f7fMehdi GHARBI<p>More information:&nbsp;</p> <p>Below is an extract of the code containing the configuration of the firmware ADC device:</p> <p><img height="183" src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1557905996809v1.png" width="461" alt=" " /></p> <p>Soft device used: S132 v5.0.0</p><div style="clear:both;"></div>
