I'll be using one of the analog in to monitor a signal. I'll be capturing positive voltage spike (5us spike) around 3v but the I notice that there are also negative spikes (-3v). Would the negative spikes damage the A/D?
I have try to use a diode but the signal is too weak that even the positive spike can't pass through. It may also that the diode I have is not fast enough to respond to a 5 us signal. I'm planning to just directly connect it to the analog input I just want to make sure that it won't damage the A/D.Thanks
