7314中文资料意法半导体数据手册PDF规格书

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.
