NJW1195A  
4-Channel Electronic Volume with Input Selector  
■ GENERAL DESCRIPTION  
■ PACKAGE OUTLINE  
The NJW1195A is a 4-channel electronic volume with  
4-in 2-out stereo audio selector. It performs low noise and  
low distortion characteristics with resistance ladder circuit.  
The NJW1195A is also available for 2-channel differential  
transmission electronic volume with 2-in 1-out stereo audio  
selector by a differential transmission select function.  
All of functions are controlled via three-wired serial bus.  
Selectable 4-Chip address is available for using four chips  
on same serial bus line.  
NJW1195AV  
It’s suitable for two-channel stereo system and or  
multi-channel audio system.  
At the volume attenuated, the NJW1195A improves low  
distortion compared with NJW1195. Furthermore, the  
NJW1195A supports both single power supply operation  
and dual power supply operation.
