DESCRIPTION  
AGND  
TREBLE_L  
TREBLE_R  
The TDA7466 is a volume tone (bass middle and  
treble) balance (Left/Right) processors with stereo  
SRS and voice canceller for quality audio applica-  
tions in car radio, Hi-Fi, TV systems.  
D96AU445A  
It reproduces SRS (Sound Retrieval System)  
sound by external components and surround  
sound by using phase shifters and a signal ma-  
trix. The AC signal setting is obtained by resistor  
networks and switches combined with operational  
amplifiers according to the SRS laboratories  
specification. Control of all the functions is ac-  
complished by serial bus.  
Thanks to the used BIPOLAR/CMOS Technology,  
Low Distortion, Low Noise and DC stepping are  
obtained.
