PRODUCT:  
Silicon monolithic integrated circuits  
Stereo Class-D Power Amplifier For Speaker  
TYPE:  
BD5431EFS  
HTSSOP-A44  
PACKAGE:  
FEATURES:  
1) Differential Analog / PWM inputs  
2) High efficiency and low heat generation eliminates external heat-sinks  
3) Eliminates pop noise generated when the power supply goes on/off, or when the power supply is  
suddenly shut off  
4) High quality muting performance is realized by using the soft-switching technology  
5) Incorporates a master/slave function that enables synchronous operation when several  
units are used simultaneously  
6) Allows the internal PWM sampling clock frequency to be adjusted  
○Absolute maximum ratings (Ta=25℃)
