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.
