Product Summary
The TDA7313D 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 external loudness function are provided. Control is accomplished by serial I2C busmicroprocessor interface. The AC signal setting of the TDA7313D is obtained by resistor networks andswitches combinedwith operationalamplifiers. Thanks to the used BIPOLAR/CMOS Tecnology, LowDistortion, Low Noise and Low DC stepping are obtained.
Parametrics
TDA7313D absolute maximum ratings: (1)VS, Operating Supply Voltage: 10.2 V; (2)Tamb, Operating Ambient Temperature: -40 to 85℃; (3)Tstg, Storage Temperature Range: -55 to +150℃.
Features
TDA7313D features: (1)input multiplexer: 3 stereo inputs; selectableinput gain for optimal adaption to different sources; (2)input and output for external equalizer or noise reduction system; (3)loudness function; (4)volumecontrol in 1.25dB steps; (5)treble and bass control; (6)four speaker attenuators: 4 independent speakerscontrol in 1.25dB steps for balance and faderfacilities; independentmute function; (7)all functions programmable via serial I2C bus.
