Hi, i want to detect a pulse with ns and 50mV amplitude. You need to amplify the pulse to make it bigger – but more details are required.
I don’t know how long a pulse needs to be to guarantee it triggers an interrupt? Should i buy another one? Mikebits Well-Known Member Sep 5, The LM is too slow for amplifying a nS pulse.
Try a high-speed opamp. Maybe this is the problem: View attachment You are at 5V and minimum trigger width is ns. On the analogue side, a simple high speed op-amp comparator will do.
or Timer as a One-Shot
You bias the reference minus some from the incoming signal. Can post an LTSpice sim when I get around to it.
How did you determine your pulse width is ns? Mikebits Well-Known Member Sep 6, Maybe from the title of the thread – detect pulse of ns and 50mv. Mikebits Well-Known Member Sep 7, You must log in or register to reply here.
