I/O
O
Power Output pin #1
Power supply pin for power output stage #2
−
I
Stand-by control pin. When this is "L", circuit current is
reduced.There is the pull-down resistor:50Kohm(typ.).
I
PWM input pin #1 ( for phase compensation)
I
Analog input #1. The gain is depended on the external
resistance .
I/O
A capacitor is connected so that it may not be influenced of
power supply change(Ripple Filter).
I
Control pin for PWM carrier frequency
GND pin for analog block
−
I/O
Capacitor connection pin for analog block reference
voltage source
O
Protection Timer pin. At protection mode,the output
becomes "L"-level.
(The timing capacitor is connected)
I
SE operation
I
BTL operation
I
PWM input pin#2 ( for phase compensation)
I
Mute control pin. When this is "L", it becomes mute status.
Power supply pin for power output stage #2
−
O
Power Output pin #2
Ground pin for power output stage #2
−
I/O
Capacitor connection pin for bootstrap
O
Built-in power supply pin for internal digital block.
I/O
Capacitor connection pin for bootstrap #1
Ground pin for power output stage #1

65／127
Description
Analog input #2(as same as IN1)
W
hen this is connected to DVDD pin via
the resister, Reversed signal of OUT1 is
output to OUT2.
