Hi,
I'm using the optocoupler HCNR200 and I need to know how I can to use it for measurement 220 VAC, because I'm probing the circuit dual with two LM158 and two HCNR200, but the circuit not working.
(The circuit that I use is of the figure 3 of the application note 1357 of Agilent technologies)
If you can help me, very thank.
