https://devzone.nordicsemi.com/f/nordic-q-a/18556/nrf52-saadc-current-vs-acquisition-timeI am using SAADC with TIMER3 and PPI, sampling 12bits at 250Hz. When I use 10uS acquisition time, the average current consumption is 300uA lower than when using 3uS or 5uS acquisition times. What could explain that shorter acquisition time takes moreen-USTelligent Community 13Fri, 23 Dec 2016 12:01:40 GMThttps://devzone.nordicsemi.com/thread/71614?ContentTypeID=1Fri, 23 Dec 2016 12:01:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0c508054-1242-4283-8c89-0b3f33c4c5d1J&#248;rgen Holmefjord<p>Hi,</p> <p>This can be related to <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.Rev1.errata/anomaly_832_74.html?cp=2_2_1_0_1_14">PAN 74</a>, potentially there is not workaround for this implemented in the SAADC driver. It has been reported internally and should be fixed in future releases.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
