Description :
The TDA7439DS, TDA7439 is a volume, tone (bass, mid-range and treble) and balance (left/right) processor for high-quality audio applications in car-radio and Hi-Fi systems. Selectable input gain is provided. All the functions are controlled by serial bus.
The AC signal setting is obtained by resistor networks and switches combined with operational
amplifiers. The TDA7439 employs BIPOLAR/CMOS technology to provide low distortion, low noise and DC stepping.
Features
1. Input multiplexer
– four stereo inputs
– selectable input gain for optimal adaptation to different sources
2. Single stereo output
3. Treble, mid-range and bass control in 2-dB steps
4. Volume control in 1-dB steps
5. Two speaker attenuators:
– two independent speaker controls in 1-dB steps for balance facility
– independent mute function
All functions are programmable via serial bus
