ORDERING NUMBER: TDA7449L  
DESCRIPTION  
The TDA7449L is a volume control and balance  
(Left/Right) processor for quality audio applica-  
tions in TV systems.  
Selectable input gain is provided. Control of all  
the functions is accomplished by serial bus.  
works and switches combined with operational  
amplifiers.  
Thanks to the used BIPOLAR/CMOSTechnology,  
Low Distortion, Low Noise and DC stepping are  
obtained.  
The AC signal setting is obtained by resistor net-
