Hello,
I need to convert some analog signals from -10,10V range to 0-5V range to interface with a microcontroller. I prototyped something on a breadboard but it did not work well so I modified it and made the attached schematic.
What I actually did is that I reproduced AD628 chip internals using TL082 amplifier. All the values of the components are specified in the eagle file attached. Also, I added a little module to obtain a reference value of 2.5V. Vcc is 5V.
Please have a look and tell me if it looks ok for you. I'm quite a noob in electronics. I understand basic principles but it's not my domain, so I'd appreciate any help and suggestions.
