TDA7342  
Digitally controlled audio processor  
Features  
Input multiplexer  
– Two stereo and one mono inputs  
– One quasi differential input  
– Selectable input gain for optimal adaptation  
to different sources  
Fully programmable loudness function  
LQFP32  
Volume control in 0.3dB steps including gain  
up to 20dB  
Zero crossing mute, soft mute and direct mute  
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  
Four speaker attenuators  
– Four independent speakers control in  
1.25dB steps for balance and fader  
facilities  
– Independent mute function  
All functions programmable via serial I2C bus  
implemented. The soft Mute function can be  
activated in two ways:  
1. Via serial bus (Mute byte, bit D0)  
2. Directly on pin 21 through an I/O line of the  
microcontroller  
Description  
The audioprocessor TDA7342 is an upgrade of  
the TDA731X audioprocessor family.  
Very low DC stepping is obtained by use of a  
BICMOS technology.
