hello
I have receive two new HCNR201, and i have some news about my circuit !!
the good news is that my circuit works but just for about 20-30 second.
After, I need to shut off the supply and wait a few moment before shut on again the supply and the circuit works for 20-30s.
After this time, i have no voltage at the output. i have try with just one HCNR201, because i don't want (just in case) to damage the second HCNR201.
Do you know where is the problem ? because i have no idea
the second problems is that i have a linearity until 50mV. when my input is bigger than 50mV in the output i have already 500mV, i think that i need to change a resistor (maybe 1.2k by 1k).
So i begin to be happy because the circuit begin to works
but the first problem is a big problem
thank you.
