NJW1140  
PRELIMINARY  
AUDIO PROCESSOR with SRS  
GENERAL DESCRIPTION  
PACKAGE OUTLINE  
The NJW1140 is a sound processor includes all of the  
functions required to process the audio signal for TV, such  
as tone control, balance, volume, mute, and AGC functions.  
Also the NJW1140 performs SRS 3D Stereo which  
regenerates 3D surround sound with only two speakers.  
All of the internal status and variables are controlled by  
I2C BUS interface.
