Product Summary

The TDA7449 is a volume tone (bass and treble) balance (Left/Right) processor for quality audio applications in TV systems. Selectable input gain is provided. Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
