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.

This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
