voltage spike detector
voltage spike detector
(OP)
Is there a circuit out there (instead of an oscilloscope) that can detect higher than 28V voltage spike. This circuit should have an indicator (LED) that a greater than 26 Volts spike has been detected. I expect the spike to be 100 nanoseconds.
Thanks in advance.
Thanks in advance.

This circuit must detect a voltage spike greater than ...say 26volts and if it detects one, there should be a way of knowing it like a simple LED.
I tried to use a comparator but op-amps operate at not more than 10MHz response and what I know is that , spike ranges at 10-100 nanoseconds that is why we need high bandwidth scopes w/ trigger to detect one.

Is this one piece or for production (How much may it cost?)
Is it enough to indicate/store one event or do you need
more info ? What ?

Are you speaking about a 28 V spice superimposed on 26V DC or only 2V ?
What do you want to do if there are more spikes ?
What about their amplitudes and durations ?
