I am doing a design with an LM380N as a PC audio amplifier. The audio input connects to a jack plug input.
I would like to add some extra ESD protection. Usually I would clamp the input to the supply rails and/or use a zener, but I read in the absolute maximum ratings section that the maximum input voltage is +/-0.5V. This is really low.
How do you protect such an input without affecting the signal?
Thanks in advance for any help.
