Audio Signal Tracer With LM386

Tuesday, December 15th, 2020 - Electronic Tools

The function of the circuit is an audio signal tracer to trace the audio signal to troble shooting time. The series of audio signal trace is essentially a low-power mono amplifier. Amplifier circuits for signal tracer uses the LM386 IC power amplifier with a supply voltage of +9 Volts DC from the batteries. The signal amplifier circuit tracer comes with volume and gain controls for tracing a weak signal. Tracer signal amplifiers in the circuit does not require a heat sink due to low power consumption and the burden that is placed too little.
