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.

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)

· STBY/REG STBY

STBY is standby control terminal for 4ch BTL.

REG STBY is standby control terminal for regulator.
