5. Popping noise reduction during power-off
The power supply line can be directly controlled ON and OFF without using the mute function. However, when using
a high supply voltage, the shock noise and aftersound during power-off tends to worsen. One method of coping with
this is to connect a capacitor between Pin 2 (VCC) and Pin 3 (MUTE) so that the auto mute function operates during
power-off.

6. Input coupling capacitor (Cin)
Cin is an input coupling capacitor, and is used for DC cutting. However, this capacitor is also used to improve the ripple
rejection ratio, which changes according to the capacitance value (recommended value = 1
µF). In addition, this
capacitor also affects the transient response characteristics during power-on and when mute is canceled, so the constant
should be set in consideration of these characteristics.
Design reference value = approximately 0.33 to 3.3
µF
• Ripple rejection ratio : Increasing the capacitance value increases the rate, and reducing the value reduces the rate.
• Rise response speed : Increasing the capacitance value reduces the speed, and reducing the value increases the
speed.
• Popping noise : Increasing the capacitance value reduces the noise, and reducing the value increases the noise.
7. Output coupling capacitor (Cout)
Cout is an output coupling capacitor used for DC cutting. However, this capacitor, Cout, in combination with load
impedance RL forms a high-pass filter and attenuates the low frequency signals. Take into account the cutoff frequency
when determining the capacitance value. In addition, normally a chemical capacitor is used for this capacitor, but the
capacitance value of chemical capacitors decreases at low temperatures, so the value should be set in accordance with
this characteristic.
The cutoff frequency is expressed by the following formula.
fc = 1/(2
π × RL × Cout)
8. Output phase compensation capacitor (Cosc)
The Cosc capacitor is used to prevent output oscillation. Use a ceramic capacitor (recommended value = 0.1
µF) with
good high frequency characteristics, and locate this capacitor as close to the IC as possible.
9. Power supply capacitor (CVCC)
The CVCC capacitor is used to suppress the ripple component of the power supply line. Normally a chemical capacitor
(recommended value = 10
µF) is used for this capacitor. However, chemical capacitors have poor high frequency
characteristics, so when using a CPU, DSP or other IC that generates digital noise in the set, it is recommended that a
power supply bypass capacitor (ceramic capacitor, recommended value = approximately 0.1
µF) be added to reject
high-frequency components. Locate this bypass capacitor as close to the IC as possible.
10. NC pin treatment
Since the NC pins (pins 5 to 10) are connected to nothing internally, they may be left open. To increase the heat
dissipation efficiency, however, it is recommended that the NC pins should be connected to the GND line.
