hi all.
i have an analog signal which i want to sample and send to PC with a micro controller or some thing else.
the analog signal comes from out side the board and user can be connect the input to any thing.
i want to protect the pc and the board from risky circumstances like:
over voltage like 220 volt ac and inverse connection and ...
the BW is about 50 mhz and maximum acceptable voltage around 50V. just like an oscilloscope.
can you help me with this?
