Monolithic Linear IC  
For Home Audio Use  
LA4631VC  
2-Channel SE AF Power Amplifier  
Overview  
The LA4631VC built-in a 2 channel single-ended output power amplifier that a power supply voltage range is wide and  
has additionally the standby function to reduce the current drain. It is a power amplifier IC suitable for driving speaker of  
various audio system equipments, which is especially useful for products that use batteries.  
Functions  
• Output power = 4.5W (typical)  
• Built in standby function (Pin5)  
• Built in thermal suht down circuit
