The TDA7439 is a volume tone (bass, middle and
treble) balance (Left/Right) processor for quality
DESCRIPTION
audio applications in car-radio and 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
amplifiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are
obtained
