2 DESCRIPTION
The TDA7430/TDA7431 is volume tone (bass middle
and treble) balance (Left/Right) processors voice
canceller for quality audio applications in car radio
and Hi-Fi systems.
They reproduce surround sound by using pro-
grammable phase shifters and a signal matrix.
Control of all the functions is accomplished by se-
rial bus. The AC signal setting is obtained by resis-
tor networks and switches combined with
operational amplifiers. Thanks to the used BIPO-
LAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are
obtained.
