LA4743B  
45 W Four-Channel (Bridge Circuit) Power Amplifier  
Overview  
Package Dimensions  
The LA4743B is a 45 W 4-channel power amplifier IC for  
car stereo systems. It features a built-in bridge circuit and  
the ability to radically reduce the number of external  
components required. It is also pin compatible with the  
LA4743A, which differs in the amount of gain provided.
