DESCRIPTION
The TDA7429 is volume tone (bass middle and tre-
ble) balance (Left/Right) processors for quality audio
applications in TV and Hi-Fi systems.
It reproduces surround sound by using programma-
ble phase shifters and a signal matrix. 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 ampli-
fiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are
obtained.
