DESCRIPTION
The TDA7318 is a volume, tone (bass and treble)
balance (Left/Right) and fader (front/rear) processor
for quality audio applications in car radio and Hi-Fi
systems.
DIP28
SO28
ORDERING NUMBERS:
TDA7318
TDA7318D
Selectable input gain is provided. Control is accom-
plished by serial I²C 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 Low DC stepping are
obtained.
