4 / 6 page LA4627 No.6501-4/6 3. FILTER (decoupling) pin (pin 8) The pin voltage is about 1/2 VCC. 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. 4. P.P (pulse noise) pin (pin 9) Pin 9 pin voltage ≈ VCC - VCE (about 0.3 V) - 5.6 V + 5.6 V 2 k Ω • The recommended value for the P.P capacitor is 4.7 µF. 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 8 (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.
