5 / 14 page 273 Audio ICs BA3430S / BA3430F / BA3430FS FMeasurement circuit FAudio signal amplification circuit (1) Input switch circuit This circuit switches between head A and head B as needed for the auto reverse function. A 10k Ω or less resistor must be connected to the input pin to limit the input current. Equivalent circuit schematic The electrolytic capacitor between the input pin and ground is for preventing switch noise. Although it is pos- sible to prevent switch noise in the audio output without this capacitor by using the mute circuit, switch noise in the mute detection circuit will not be prevented and noise will be recognized as a song.
