connected to the LA42052 front end.
C3
C4
C5
: The recommended value for the Ripple filter capacitor is 100μF.
: The recommended value for the P.P capacitor 4.7μF. It is a capacitor for there being small Pop sound.
: Power supply capacitor.
C6, C7 : The recommended value for the output capacitor is 470μF.
1. Standby Function (Pin 5)

2. Ripple filter and Mute function (Pin 1)
Pin voltage is approx. 1/2 V
CC
The recommended value for the Ripple filter capacitor is 100µF.
Muting :
The output signal can be controlled by connecting pin 1(Ripple filter) to ground via a resistance of 300 to 500Ω.
If resistance is higher than 750Ω, the suppression ratio will decrease.
3. Input Pin (Pin 2,4)
Voltage at the input pins is approx. 2V (about 1.4V)
BE
Determine the polarity orientation of these capacitors based on the DC current from the circuit
Connected to the LA42052 front end.
Input resistance is approx. 30kΩ (typ)
The recommended value for the input capacitor is 1.0µF.
4. P.P (Pin 6)
The Pin 6 is Terminal for there being small pop sound
at the time of power supply ON/OFF.
C4 recommends 4.7µF.

Usage Notes
1. Lightening (power supply - output short-circuit) and ground fault (GND - output short-circuit) protective circuits are
not incorporated. Due care must be taken during handling of the product.
2. The thermal protective circuit is incorporated and activated when the junction temperature (Tj) rises above about
160°C.
This circuit controls the output gradually to the attenuated condition.
3. Always ensure the sufficient margin for the supply voltage, etc. to operate the product within the area where the
maximum rating will never be exceeded. Namely, the maximum rating may be exceeded due to the slight change in
conditions, resulting in damage, if the product is used around the maximum rating.
