3. FILTER (decoupling) pin (pin 7)
The pin voltage is about 1/2VCC.
The recommended value for the filter capacitor is 100
μF.
The pulse noise that occurs when the standby pin is set low (power off) will be degraded if a value under 100
μF is
used.

The recommended value for the P.P capacitor is 4.7μF.
The pulse noise that occurs when the standby pin is set low (power
off) will be degraded if a value under 2.2
μF is used.
Furthermore, if a value over 10
μF is used, the signal may not be cut
off and sound may remain audible when the standby pin is set low
(power off).
5. MUTE (Muting)
The output signal can be controlled by shifting the pin 7 (FILTER) level towards ground with a 300 to 500
Ω resistor.
However, note that the degree of suppression is reduced if a value of 750
Ω or more is used.
