Hello,
I just finish building a small circuit utilizing an opto coupler, the
mct6.
I use an LM331to translate voltage to frequency, that works, but when
I add the optocoupler in , it do not keep the frequency intact. I mean
it has huge rise and slow time. Basiclaly If I use a pic chip to count
the frequency it is basically tell me its high all the time. Is there
an opto coupler that can react faster ? or this is it. I am trying to
make a voltage checker circuit using two different grounds.
thanks
ken
