DESCRIPTION
The audioprocessor PIN CONNECTION PQFP44 and TQFP44 ORDERING NUMBERS: TDA7437 (PQFP44) TDA7437T (TQFP44) Due to a highly linear signal processing, using CMOS-switching techniques instead of standard bipolar multipliers, very low distortion and very low noise are obtained. Several new features like softmute, and zero-crossing mute are implemented. 44 43 42 41 40 39 38 37 36 35 34 TREB_R IN_R MUXOUT_R LOUD_R DIFFGND_R DIFF_R STEREO4_R STEREO1_R STEREO2_R STEREO3_R MONO 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 DIFFGND_L STEREO4_L STEREO1_L STEREO2_L STEREO3_L MUXOUT_L LOUD_L DIFF_L MID_LI CSM IN_L 33 32 31 30 29 28 27 26 25 24 23 OUT_RF OUT_LR MID_RI MID_RO OUT_RR SMEXT BASS_RO BASS_RI BASS_LO BASS_LI MID_LO OUT_LF D96AU435A TREB-L PAUSE DGND AGND DVDD ADDR AVDD CREF SDA SCL December 1999 1/23 TDA7437 ABSOLUTE MAXIMUM RATINGS
