Description

The TDA7345 is a volume tone (bass and treble) balance (Left/Right) processor for quality audio applications in car radio and Hi-Fi systems.

It reproduces surround sound by using phase shifters and a signal matrix. Control of all the functions is accomplished by serial bus.

The AC signal setting of the TDA7345 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.
