circuit diagram
In this post I make a 10 watt stereo amplifier. Now watch the circuit diagram and follow my steps for make this amplifier. First you need a TEA2025B ic. Connect 100uf capacitor's [+] with ic's 3 no pin and connect capacitor's [-] with ic's 2 no pin. Then connect another 100uf capacitor's [+] with ic's 14 no pin and connect capacitor's [-] with ic's 15 no pin. Then connect 470uf capacitor [+] pin with ic's 2 no pin and capacitor [-] is 1st speaker output. Then connect another 470uf capacitor [+] pin with ic's 15 no pin. And capacitor [-] pin is 2nd speaker output. Then you need 3 pcs 100uf capacitor. Connect 100uf capacitor [+] pin with ic's 6, 8 and 11 no pin. and capacitor [-] pin connect with gnd. Then connect 104j capacitor with ic's 7 and 10 no pin. And here is audio input. Then short all gnd pin of ic. Short ic's 4, 5, 9, 12, 13 no pin by a wire. Then connect a 1000uf capacitor's [+] with ic 16 no pin and capacitor's [-] connect with gnd. And here is power input (16 no pin). for power supply you can input 3- 15 volt dc. Now your circuit is ready. play songs on this circuit.
Thank you,
