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.
