 I have trouble reading saadc data with an amplitude of 10 &amp;#181;V - 100 &amp;#181;V with a sampling rate of 1K Hz by using nrf52832. I was wondering if I could get advice/help to solve this issue. 
 From my understanding, I need to lower the reference</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 05 Aug 2021 11:14:29 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/78254/reading-saadc-signals-that-are-in-the-range-of-10--100-v-in-the-sampling-frequency-of-1khz" /><item><title>RE: Reading SAADC signals that are in the range of 10- 100μV in the sampling frequency of 1kHz</title><link>https://devzone.nordicsemi.com/thread/323509?ContentTypeID=1</link><pubDate>Thu, 05 Aug 2021 11:14:29 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:be275fbc-9d41-4ca6-abb3-1d529ca8bdf6</guid><dc:creator>haakonsh</dc:creator><description>&lt;p&gt;The SAADC cannot resolve that signal as its amplitude is far too low, the signal will be buried in offset and noise.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;What you need is an instrumental amplifier that boosts the signal to a more appropriate level for the SAADC.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;The SAADC can handle up to 200ksps at 3µs acquisition time.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
