Input coupling capacitors.
Boost switch on/off impulse noise reduction capacitor.
Mute switch on/off impulse noise reduction capacitor.
Reference bias (V
Beep input coupling capacitor. Be careful not to attenuate the beep tone signal.
Ripple filter capacitors.
Reference bias (V
Boost switch on/off impulse noise reduction capacitor.
Power supply line decoupling capacitor.
Low pass filter capacitor in the bass boost circuit. The amount of bass boost depends on the value of this capacitor.
Output oscillation prevention capacitors. We recommend using Mylar capacitors. Since the oscillation stability
varies depending on the PCB layout and other factors, we recommend a value of at least 0.1 µF for these capacitors.
Output capacitors. Low band attenuation increases with lower capacitances.
Smoothing resistor for the boost switch on/off transition. Note that using a smaller value will increase the idling
current when the boost switch is off.
Output oscillation prevention resistors.
