ORDERING NUMBERS: TDA7437 (PQFP44)  
TDA7437T (TQFP44)  
BASS AND TREBLE CONTROL  
Due to a highly linear signal processing, using  
CMOS-switching techniques instead of standard  
bipolar multipliers, very low distortion and very  
low noise are obtained. Several new features like  
softmute, and zero-crossing mute are imple-  
mented.  
The soft Mute function can be activated in two  
ways:  
1 Via serial bus (Mute byte, bit D0)  
FOUR SPEAKER ATTENUATORS

DESCRIPTION  
The audioprocessor TDA7437 is an upgrade of  
the TDA731X audioprocessorfamily.  
Very low DC stepping is obtained by use of a  
BICMOS technology.
