TDA7463D

® TDA7463D LOW VOLTAGE TONE CONTROL DIGITALLY CONTROLLED AUDIO PROCESSOR 1 STEREO INPUT 1 STEREO OUTPUT TREBLE BOOST BASS CONTROL BASS AUTOMATIC LEVEL CONTROL VOLUME CONTROL IN 1dB STEPS MUTE STAND-BY FUNCTION SOFTWARE CONTROLLED ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The TDA7463 is a volume tone (bass and treble) processor for quality audio applications in Low voltage supply portable systems. Bass ALC (Automatic Level Control) function can be adjusted by a dedicated pin. The control of all the functions is accomplished by serial bus. BLOCK DIAGRAM R5 5.6K C12 3.3nF 100nF C11 SO16 ORDERING NUMBER: TDA7463D The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained. 100nF C10 TREBLE-R BASSI-R BASSO-R RB -63dB CONTROL TREBLE 50K BASS C1 0.47µF IN-R 0/-10dB x1 x5 OUT-R VS BASS_ALC CONTROL C2 0.47µF ALC R1 1MΩ SCL HALF_WAVE RECTIFIER + I2C BUS DECODER + LATCHES SDA R3 1KΩ VS R4 1KΩ I2C 1 2 3 4 VS DGND SCL SDA C3 0.47µF IN-L 50K -63dB CONTROL TREBLE BASS 0/-10dB x5 x1 OUT-L RB VREF SUPPLY VS C8 100nF VS C9 100µF D96AU482B C4 3.3nF TREBLE-L BASSI-L C5 100nF BASSO-L C6 100nF GND CREF C7 22µF R2 5.6K May 2002 1/12 TDA7463D ABSOLUTE MAXIMUM RATINGS Symbol VS Tamb Tstg Operating Supply Voltage Operating Ambient Temperature Storage Temperature Range Parameter Value 5 -10 to 85 -55 to 150 Unit ...
