please find attached the circuit diagram that i used. The red box is the one that omitted.
In fact, my phone is connected to the modem via the rj11 cable, the service is voip. And the capacitor of 275V is the 0.2uF. I do not know whether the problem lies in my circuitry.
I am doing a small project which involves the use of ht9032d connected to the phone line and the output will be connected to the arduino. My phone line gives 48.2V. I have implemented the circuit just as in the datasheet. A slight change is that i am using 275 V capacitor. I am not getting any...
