■ ALL FUNCTION ARE PROGRAMMABLE VIA
SERIAL BUS

2 DESCRIPTION
The TDA7438 is a volume tone (bass, middle and
treble) balance (Left/Right) processor for quality
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 networks
and switches combined with operational
amplifiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are
obtained.
