NJU7394  
Pushbutton Interface EVR  
„ GENERAL DESCRIPTION  
„ PACKAGE OUTLINE  
The NJU7394 is a pushbutton interface electronic volume.  
It includes a electronic volume controller with differential input,  
attenuator function, some indicator and a stand-by function  
(Power-saving mode).  
The NJU7394 has also built-in push button interface for its  
volume UP/DOWN controls and power ON/OFF controls -  
making application possible without the use of micro-controller.  
The NJU7394 is suitable for low power application and also for  
application without micro-controller such as mobile audio player  
and cradle speaker for mobile game.
