4. P.P (pop noise) pin (6)

Voltage at pin 6 =.. 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

6

pin to Low (power 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 5 (Filter) to ground via a

resistance of 300 to 500 Ω. If resistance

is higher than 750 Ω, the suppression

ratio will decrease.
