For power supply transistor regulation, the equivalent power line resistance is 3Ω or greater.

[Precaution concerning the metal]

Select PO with a goal of a rated load/rated supply voltage of RL=3 to 8Ω and VCC=5 to 18V and design to avoid
exceeding the package Pd max of 37.5W. For heavy loads or high VCC, the drive design is involved and the power
effect deteriotates, so pay attention to these factors.

Block Diagram

Note 1 : The motor should not be connected to the power switch pin, since transient noise may appear on the amplifier

outputs when the motor is started or stopped.

Note 2 : Audio mute is enabled by connecting a 300Ω resistance between the DC pin and ground. DC bias control of

both the stereo (L ch, R ch) and BTL (super bass) channels is enabled, and all audio output signals can be
muted by controlling the MUTE pin.

Notes on using this IC

• Alw ays shor t power supply pins 9 and 16 on the copper foil of the printed circuit pattern and apply the equivalent po wer
supply voltage.

• Pin 17 is designed for the power switch.
It can be switched on and off with a small current capacitance switch, but the point to watch out for is tha t if the voltgae
loss between pins 17 and 18 is too large, there may be problems in the biasing and the power may drop.

• When switching with a transistor, the general practice is to insert a PNP transistor between pins 17 and 18.

Notes on Mounting Radiator Fin

1. The tightening torque should be in the range of 39 to 59N · cm.

2. The distance between screw holes of the radiator fin must coincide with the distance between screw holes of the IC.
With case outline dimensions L and R referred to the screws must be tightened with the distance between them as
close to each other as possible.

3. The screw to be used must ha v e a head equivalent to the one of truss machine screw or binder machine screw defined
by JIS. Washers must be also used to protect the IC case.

4. No foreign matter such as cutting particles shall exist between heat sink and radiator fin. When applying grease on the
junction surface, it must be applied uniformly on the whole surface.

5. IC lead pins are soldered to the printed circuit board after the radiator fin is mounted on the IC.
