I/O Description
I Active high. If it is high, PWM output is activated after power
ON Mute Time, TM . Otherwise (Default = HIGH)
I Triangle wave generator enable input
B Triangle wave I/O
I Mute control input. It is also used for external protection.
Active low. Low state is muted state.
O Logic power supply pin (internal generated)
B L-channel amp capacitor connected pin for Phase & gain
O L-channel pre-amp output pin for gain setting
I L-channel pre-amp input pin
P L-channel sound ground
P R-channel sound ground
I R-channel pre-amp input pin
O R-channel pre-amp output pin for gain setting
B R-channel amp capacitor connected pin for Phase & gain
I P-MOS gate delay setting pin
I N-MOS gate delay setting pin
O Regulated voltage output pin for internal current bias
I Triangle wave magnitude setting input
I Time delay capacitor pin for internal use
P Negative power supply pin
I Soft clipping low level input
I R-channel current feed back input 2
I R-channel current feed back input 1
I R-channel voltage feed back input
P Control block ground
P Reference block ground
I Power Down Detection
I The operating voltage detection pin of the external
MOSFET. When its function is not used, this pin must be
tied to VCC and about 0.1uF is connected to GND
O R-channel N-MOS switching output (PWM)
O R-channel P-MOS switching output (PWM)
- NC (Test pin for evaluation)
- NC (Test pin for evaluation)
O L-channel P-MOS switching output (PWM)
O L-channel N-MOS switching output (PWM)
