DESCRIPTION
The TDA7429L is volume tone (bass middle and tre-
ble) balance (Left/Right) processors for quality audio
applications in TV and Hi-Fi systems, providing also
an additional subwoofer control.
The AC signal setting 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 ob-
tained.
