- INDEPENDENT MUTE FUNCTION  
ALL FUNCTIONS PROGRAMMABLE VIA SE-  
RIAL I2 CBUS  
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, zero-crossing mute and pause detector  
are implemented.  
The Soft Mute function can be activated in two  
ways:  
DESCRIPTION  
The TDA7348 is an upgrade of the TDA7318  
audioprocessor.  
Thanks to the used BIPOLAR/CMOS technology,  
very low distortion, low noise and DC-stepping  
are obtained.  
1 Via serial bus (bit D0, Mute Byte)  
2 Directly on pin 22 through an I/O line of the  
microcontroller  
Very low DC stepping is obtained by use of a  
BICMOS technology.
