4. P.P (pulse noise) pin (pin 9)
Pin 9 pin voltage
≈ VCC--VCE (about 0.3V) --5.6V
+ 5.6V
2
The recommended value for the P.P capacitor is 4.7
F.
The pulse noise that occurs when the standby pin is set low (power off) will
be degraded if a value under 2.2
F is used.
Furthermore, if a value over 10
F 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 8 (FILTER) level towards ground with a 300 to 500
resistor.
However, note that the degree of suppression is reduced if a value of 750
or more is used.
