We are directly measuring force using an array of strain gauges. Of course we will need an ADC to accomplish this, I’m just wondering what theen-USTelligent Community 13Thu, 30 Jul 2020 18:08:35 GMThttps://devzone.nordicsemi.com/thread/262464?ContentTypeID=1Thu, 30 Jul 2020 18:08:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dacc4917-453c-41e7-811f-39e37c632632drewvigne<p>Good point and something to consider.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/262266?ContentTypeID=1Wed, 29 Jul 2020 21:09:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:70749f06-fd56-46f5-8aa0-fe884066b623awneil<p>The hard part of anything like this is getting the <em>analogue</em> bit right.</p> <p>You will never achieve the full potential of any ADC if the <em>analogue</em> signal is sub-optimal before it reaches the ADC&#39;s inputs!</p> <p>The HX11 is not just an ADC - it also has all the analogue&nbsp;signal conditioning built in.</p> <p>Unless you&#39;re an analogue design expert,&nbsp; this would certainly be the way to go.</p> <p>EDIT</p> <p>I&#39;m sure the HX11 is not the only such chip available - it shouldn&#39;t be hard to have one that has a standard interface.</p> <p>But it really makes no difference to the nRF what you choose</p><div style="clear:both;"></div>
