Hi John, Thanks for getting back to me. I was actually looking at that same ADC converter as you posted in your reply. Just looking for some clarification on a few things. What type of error would a simple resistor divider introduce into the system? I am currently using a cascaded inverting op amp system. Not really sure if this will scale the input voltage to a level that is compatible with my ADC.
The circuit diagram looks like this: [image: Inline image 1] Looking forward to your reply, Chels On Thursday, December 3, 2015 at 5:07:41 PM UTC-5, Chelsea Orefice wrote: > > Hi everyone, > > I am new to the world of using MCUs and am looking for some assistance on > a project that I am currently working on.
