I want to transform a signal ranging from -5V to +7V to a more MCU digestable 0-3.3V. I came up with the circuit you’ll find attached.</div><div><br></div><div>I have seen other approaches, where an offset reference is injected in the feedback loop, while the positive op-amp input is grounded. Are there any disadvantages to my approach or is it also valid?</div><div><br></div><div>Thank you so much!</div><div><br></div><div>I’ve been following this email list for some time now. This is my first question and first email entirely. Please bear with me.</div><div><br></div><div><br></div><div>Chris</div> <div><br></div> </div> <div id="CanarySig"> <div> <div style="font-family:Helvetica;"><div style="font-family:Helvetica;"><br></div></div> <div><br></div> </div> </div> <div id="CanaryDropbox"> </div> </body></html>
