I would like to build a protection for a sound card oscilloscope.
Here **broken link removed** they say that the inline max voltage is 0,7V
I found a circuit that do this limitation but this one said it is limiting the voltage to 12V : Buffer Hardware for xoscope
Honestly It is more likely to be the 0,7V than the 12V.
Anyone has an idea how to build a 0,7V voltage limiter ?
