DESCRIPTION
The TDA7339 is a volume and tone (bass , mid-
dle and treble) processor for quality audio appli-
cation in car radio and Hi-Fi system.
Control is accomplished by serial I
2C bus micro-
processor interface.
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
are obtained.
This is preliminary information on a new product now in development. Details are subject to change without notice.
