Can you help me to say after seeing the circuit design whether my circuit design of KIA6283 Audio Amplifier is correct or not ? Please tell your views about it to rectify my error !
Why don't you use the pcb design shown on its datasheet?
EDIT: You are using low frequency electrolytic capacitors for C6 and C7 but the datasheet says to use high frequency polyester film capacitors. So your circuit will probably oscillate at a high frequency.
As my PCB is not working at all as there is no sound present. I think I have done some mistakes in designing. As I am using realPCB of Crocodile Technology software where some sort of features is unavailable so it made these mistakes as well as my ignorance about circuitry. I am habituate with realPCB but not in any other PCB software. I am self-taught in PCB design. So may I have some weakness in this matter. If you can rectify it as I will be very much happy about your generosity.
You never told us how you are connecting all the grounds on your pcb together so I guessed that you are using a double-sided pcb with the ground connections all on one side and most of the circuit that you showed on the other side.
Then I guessed correctly.
You should use the shematic, pcb design and thick traces used on the recommended pcb design shown on the datasheet for the amplifier ICs.
