DESCRIPTION
The TDA7310 is a volume, tone (bass and treble)
and fader (front/rear) processor for high quality audio
applications in car radio and Hi-Fi systems.
Loudness and selectable input gain are provided.
The control of all fuctions is accomplished by serial
bus microprocessor interface.
The AC signal setting is obtained by resistor networks
andswitches combined with operationalamplifiers.
Thanks to the used BIPOLAR/CMOS Tecnology,
Low Distortion, Low Noise and DC stepping are ob-
tained.
