DESCRIPTION

The TDA7314isa volume, tone (bass and treble)
balance (Left/Right) and fader (front/rear) processor
for quality audio applicationsincar radio and Hi-Fi
systems.
Selectable input gain and internal loudness function
are provided. Controlis accomplishedby serial bus
microprocessor interface.
TheAC signal settingis obtainedby resistor networks
andswitches combinedwith operationalamplifiers.
Thanksto the used BIPOLAR/CMOS Tecnology,
Low Distortion, Low Noise andDC steppingareob-
tained.
