Precaution Use

(4ch BTL)

• Input stage

Minimum input DC voltage range for buffer is 0.2 V

• Driver stage

Each channel driver consists of BTL configuration linear amplifier.

Voltage gain is fixed: Gv = 15.2dB

• VCIN terminal

VCIN is reference voltage terminal for input signal

• GND

Pin 8~10 and Pin 27~29 are connected to FIN through inner lead frame.

Each FIN are not connected each other also.

The heat of power dissipation is transferred to PCB, through PW-GND Pin. PW GND is connected to substrate

of Pellet to connected copper foil area as large as possible.

• VCC1/VCC2

Pin 14 and pin 23 are not connected through AL layer on chip.

(H-Bridge)

• VR/VM terminal

VR terminal is control for H-brige dynamic range. I36 = 30 mA (Brake Mode)

VM terminal is VCC terminal for H-Bridge.

• STBY/REG STBY

STBY is standby control terminal for 4ch BTL.

REG STBY is standby control terminal for regulator.
