DESCRIPTION
The TDA7319 is a volume and tone (bass , mid-
dle and treble) processor for quality audio appli-
cationin car radio and Hi-Fi system.
Control is accomplished by serial I
2
C bus micro-
processorinterface.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers.
Thanks to the used BIPOLAR/MOS Technology,
Low Distortion, Low Noise and Low Dc stepping
areobtained.
