I would like to read high voltage (~100V DC) using C2000 launchpad for a closed loop operation of a power converter. Since the launchpad cannot take such high voltage, I must use a signal conditioning circuit. Most people suggest me to use a voltage divider. But i think that even if i use voltage divider, I must isolate the high voltage from the launchpad. How safe is to use a voltage divider? Could some one help me on this issue?
