Point of Application Board Design

1. Notes on Application Board’s Pattern Design

• For increasing stability, the connected line of VCC and OUTGND is better to be made wider and

lower impedance.

• For increasing stability, it is better to place the capacitor between VCC and GND (0.1 µF) close to

IC.

• For increasing stability, it is better to place C1 to C8 and R1 to R8, which are for stopping

oscillation, close to IC.

• It is better to place the grounding of resistor (Rg), between input line and ground, close to INGND

(Pin 12) because if OUTGND is connected to the line between Rg and INGND, THD will become
worse due to current from OUTGND.

2. How to Reduce the Popping Noise by Muting Circuit

At normal operating circuit, Muting circuit operates at high speed under 1 µs.
In case popping noise becomes a problem, it is possible to reduce the popping noise by connecting

capacitor, which determines the switching time constant, between pin 10 and GND. (Following
figure 2)

We recommend value of capacitor greater then 1 µF.
Also transitional popping noise can be reduced sharply by muting before VCC and Standby are

ON/OFF.
