4. P.P (pop noise) pin (8)
Voltage at pin 8 .=. VCC – VCE (approx. 0.3V) – 5.6V + 5.6V

• The recommended value for the P.P capacitor is 4.7 µF. When capacitance is
lower than 2.2 µF, pop noise when setting the standby pin to Low (power
8
OFF) will increase.
When capacitance is higher than 10 µF, the sound will not be cut off when
setting the standby pin to Low (power OFF).
5. Muting
The output signal can be controlled by
connecting pin 7 (Filter) to ground via a
resistance of 300 to 500 Ω. If resistance
is higher than 750 Ω, the suppression
ratio will decrease.
