Sample Application Circuit

Description of External Components

These capacitors affect low-region output; if the capacitor value is reduced, the low-region output decreases. Therefore,

47 µF or more is desirable.

Mylar capacitor, which is excellent in temperature characteristics and frequency characteristics is used.

Power supply capacitor

The capacitor values depends on the power supply line loads (motor, and the like.) and transformer ripple component.

1000 µF to 2200 µF is recommended.

Standby capacitor

Pop noise reduction capacitor

Decoupling capacitor

This capacitor absorbs power supply ripples; 220 µF is recommended.

The resistor value may be varied 3.3

Ω to 1.0 Ω.

Mylar capacitor

Unit (resistance:

Ω, capacitance:F)

To large signal GND

Mylar capacitor

C + R can be added to the negative side of the output capacitor.

However, this is true only for a Sanyo-recommended board; for a set board, artwork must also be

considered.
