DESCRIPTION
The TDA7443D is a volume tone (bass and treble)
balance (Left/Right) processor for quality audio appli-
cations in Hi-Fi systems.
Selectable input gain is provided. 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 ob-
tained.
