TDA7432

TDA7432 BASIC FUNCTION AUDIO PROCESSOR ONE STEREO AND ONE MONO INPUTS MUTE FUNCTION (SOFTWARE AND HARDWARE) CONTROLLED VOLUME CONTROL IN 1dB STEP BASS AND TREBLE CONTROL IN 2dB STEP FULLY PROGRAMMABLE LOUDNESS CONTROL FOUR SPEAKER ATTENUATORS: – Independentattenuation control – Independentmute function ALL FUNCTIONS PROGRAMMABLE VIA I2CBUS DESCRIPTION The TDA7432 is a volume, tone (bass and treble) balance (Left/Right) processor for quality audio applications in car radio and Hi-Fi systems. Control is accomplished by serial bus microprocessor interface. The AC signal setting is obtained by resistor netBLOCK DIAGRAM 4.7K 100nF BINL 10 100nF BOUTL 9 SO20 ORDERING NUMBER: TDA7432D works and switches combined with operational amplifiers. Thanks to the advanced BIPOLAR/CMOS Technology, the external components have been reduced. 68nF 2.7nF LOUD_L 6 TRL 11 SPKR ATT 16 LEFT FRONT IN_L 3 MUX VOL + LOUD BASS TREBLE SPKR ATT 14 LEFT REAR MONO_IN/MUTE 4 18 S BUS DECODER + LATCHES 19 SCL SDA IN_R 2 MUX VOL + LOUD BASS TREBLE SPKR ATT SPKR ATT 15 RIGHT FRONT VS 17 SUPPLY 1 GND 10µF CREF 68nF 5 8 BINR 7 BOUTR 100nF 4.7K 12 TRR 2.7nF 13 RIGHT REAR 20 LOUD_R 100nF D95AU357A August 1996 1/10 TDA7432 ABSOLUTE MAXIMUM RATINGS Symbol VS Tamb Tstg Operating Supply Voltage Operating Temperature Range Storage Temperature Range Parameter Value 10.2 -40 to 85 -55 to +150 Unit V °C °C QUICK REFERENCE DATA Symbol VS VCL THD S/N Sc Supply Voltage Max.
