DESCRIPTION
The TDA7312 is a volume, tone (bass and treble)
balance (Left/Right) processor for quality audio appli-
cations.
SDIP30
ORDERING NUMBER: TDA7312
Control is accomplished by serial I²C bus microproc-
essor 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 Low DC stepping are
obtained.
