DESCRIPTION

The TDA7311 is a volume, tone (bass and treble)

and fader (front/rear) processor for high quality

audio applications in car radio and Hi-Fi systems.

DIP40

ORDERING NUMBER: TDA7311

Control is accomplished by serial bus microproc-

essor interface.

The AC signal setting is obtained by resistor net-

works and switches combined with operational

amplifiers.

Thanks to the used BIPOLAR/CMOS technology,

low distortion, low noise and DC stepping are ob-

tained.
