https://devzone.nordicsemi.com/f/nordic-q-a/82851/saadc-sampling-rateHello, I&#39;m using following code to read ADC values. The minimum sampling time I&#39;m able to read the ADC reliably is 60ms. I want to lower it to say 5ms or 10ms. Is there any thing I can change in the code to make this happen. I can lower the samplingen-USTelligent Community 13Fri, 17 Dec 2021 15:11:40 GMThttps://devzone.nordicsemi.com/thread/344189?ContentTypeID=1Fri, 17 Dec 2021 15:11:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e8ff9146-5351-49c5-9064-967e3bdec006ovrebekk<p>Hi&nbsp;</p> <p>It sounds a bit odd that you would be unable to use a faster sampling interval than 60ms. The ADC can sample much faster than this.&nbsp;</p> <p>Most likely the issue is related to the interrupt processing, which happens as soon as the ADC buffers fill up, but 5-10ms is not very fast for interrupts either.&nbsp;</p> <p>Do you have a lot of other activities in the application that could be delaying the processing of the interrupts?</p> <p>One thing you can do to reduce the amounf of SAADC interrupts is to increase the size of the ADC buffer, set by the&nbsp;SAMPLES_IN_BUFFER define, so that the SAADC module will do more samples before the buffers fill up and you need to process them.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
