Description

The TDA7443D is a volume tone (bass and treble) balance (Left/Right) processor for quality audio applications in Hi-Fi systems.
Selectable input gain is provided. Control of all the functions of the TDA7443D is accomplished by serial bus.
The AC signal setting is obtained by resistor net-works and switches combined with operational amplifiers.
Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
