ALL FUNCTIONS PROGRAMMABLE VIA SE-
RIAL BUS
DESCRIPTION
The TDA7430/7431 are volume tone (bass middle
and treble) balance (Left/Right) processors with
SDIP42
TQFP44
ORDERING NUMBERS: TDA7430 (TQFP44)
TDA7431 (SDIP42)
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 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.
