7314 Datasheet - STMicroelectronics

DESCRIPTION
The TDA7314 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.
Selectable input gain and internal loudness function are provided. Control is accomplished by serial bus microprocessorinterface.
TheAC signalsettingis obtainedby resistor networks andswitches combinedwith operationalamplifiers.
Thanks to the used BIPOLAR/CMOS Tecnology, Low Distortion, Low Noise and DC stepping are obtained.
