Hello,
I have a project that I am working on that involves an Arduino, and an external 16-bit analog to digital converter. I am testing op-amps and I need the output of the op-amp to go into the analog to digital converter. The problem is that the ADC card can only handle 2-5.5Vdc while the output of the op-amp will be around 10.24V. My question is how can I drop the output voltage of the op-amp without losing any accuracy? Right now my idea is to use a simple voltage divider where I can do a simple line of code in the arduino program to bring that voltage back up to the exact value that was at the output of the op-amp. For example, if my output voltage is 10.239789, I would like to divide that voltage by a certain number (depending on my resistors) and then be able to multiply it in my program to get back that 10.239789.
Would that voltage divider work? Should I make it a voltage divider with a buffer? Or is there a better option? Thank you for your time.
