TDA7439  
Three-band digitally-controlled audio processor  
Features  
! Input multiplexer  
– four stereo inputs  
– selectable input gain for optimal adaptation  
to different sources  
! Single stereo output  
! Treble, mid-range and bass control in 2-dB  
steps  
SDIP30  
! Volume control in 1-dB steps  
! Two speaker attenuators:  
high-quality audio applications in car-radio and  
Hi-Fi systems. Selectable input gain is provided.  
All the functions are controlled by serial bus.  
– two independent speaker controls in 1-dB  
steps for balance facility  
– independent mute function  
The AC signal setting is obtained by resistor  
networks and switches combined with operational  
amplifiers.  
! All functions are programmable via serial bus.  
The TDA7439 employs BIPOLAR/CMOS  
technology to provide low distortion, low noise  
and DC stepping.  
Description  
The TDA7439 is a volume, tone (bass, mid-range  
and treble) and balance (left/right) processor for
