DESCRIPTION
●The TDA7440D 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 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
