1. Muting Function (pin 22) Audio muting function is enabled when pin 22 is Low. When the time constant of the muting function is determined by R1 and C4, it should take into account the pop noise. The pop noise which is generated when the power or muting function is turned ON/OFF will vary according to the time constant. (Refer to Figure 4 and Figure 5.) The pin 22 is designed to operate off 5 V . Moreover, this terminal (pin 22) serves as the source switch of current of an internal mute circuit. And it is designed so that the discharge current of this terminal (pin 22) may serve as 200 /G6dA. The outside pull-up resistor R 1 is determind on the basic of this value. ex) When control voltage is changed in to 6 V from 5 V.

To obtain enough mute attenuation, a series resistor, R1 at pin 22 should be 47 k/G57 or more.

1. High-Side Switch Pin 25 of this device is used in concerned with VCC as a high-side switch which operates with the standby pin. Thus, both the power amp IC and the connected external unit (the hideaway unit) can be turned ON/OFF by using of the standby switch. 5. Pop Noise Suppression Since the AC-GND pin (pin 16) is used as the NF pin for all amps, the ratio between the input capacitance (C1) and the AC-to-GND capacitance (C6) should be 1:4. Also, if the power is turned OFF before the C1 and C6 batteries have been completely charged, pop noise will be generated because of the DC input umbalance. To counteract the noise, it is recommended that a longer charging time be used for C2 as well as for C1 and C6. Note that the time which audio output takes to start will be longer, since the C2 makes the muting time (the time from when the power is turned ON to when audio output starts) is fix. The pop noise which is generated when the muting function is turned ON/OFF will vary according to the time constant of C4. The greater the capacitance, the lower the pop noise. Note that the time from when the mute control signal is applied to C4 to when the muting function is turned ON/OFF will be longer. 6.
