TDA7435  
DIGITALLY CONTROLLED AUDIO PROCESSOR  
WITH LOUDSPEAKERS EQUALIZER  
INPUT  
- FOUR HIGH PASS CHANNELS  
- TWO AUX STEREO CHANNELS  
VOLUME CONTROL IN 1dB STEPS WITH  
GAIN UP TO 15dB  
SOFT MUTE AND DIRECT MUTE  
FOUR AUXILIARY CHANNELS:  
- TWO SPEAKERSCONTROL IN 1dB STEP  
- TWO CHANNELS MULTIPLEXEDWITH  
THE HIGH PASS CHANNELS  
SO28  
ORDERING NUMBER: TDA7435D  
ALL FUNCTIONS PROGRAMMABLE VIA SE-  
RIAL I2 CBUS  
A second programmable high pass filtering pro-  
vides the loudspeakersequalization.  
The soft Mute function is implemented andcan be  
activated in two ways:  
1 Via serial bus (Mute byte, bit D0)  
DESCRIPTION  
The audioprocessor TDA7435 is an upgrade of  
the TDA731X audioprocessorfamily.  
2 Directly on pin 3 through an I/O line of the mi-  
crocontroller  
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.  
Very low DC stepping is obtained by use of a  
BICMOS technology.
