Neste vídeo mostro como resolvi o problema de ruído da placa XH-M577, era um estalo forte acompanhado de um "apito". A placa usa o CI TPA3116D2, como não tive acesso ao pino de MUTE(12), pois fica embaixo do dissipador de calor, montei o circuito na trilha do pino SDZ(2) Esse pino vai ligado ao VCC através de um divisor de tensão. O circuito ON-Delay, deixa esse pino desligado por um curto período. #amplificador #Eletronica #DIY
