DESCRIPTION
The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers according to the SRS labs specificaPIN CONNECTION (Top view) LOUT RIN LIN DIG_GND SCL ADDR SDA AGND PS1 PS2 PS3 PS4 PS5 PS6 1 2 3 4 5 6 7 8 9 10 11 12 13 14 D96AU507 DIP28 ORDERING NUMBER: TDA7467 SO28 ORDERING NUMBER: TDA7467D tion. Control of all the functions is accomplished by serial bus. Thanks to the used BIPOLAR/CMOS/DMOS technology, Low Distortion, Low Noise and DC stepping are obtained. 28 27 26 25 24 23 22 21 20 19 18 17 16 15 ROUT CREF LP2 LP1 HP6 HP5 HP4 VS HP3 HP2 HP1 VREFOUT NETW2 NETW1 May 1997 1/11 HP1 HP2 HP3 HP4 HP5 PS4 PS5 PS1 LP1 25 26 LP2 9 19 22 23 24 10 11 18 20 13 14 PS6 12 BLOCK DIAGRAM PS2 PS3 HPF1 HPF2 LPF1 0.15µ F FIX 31.5dB control 3 L-IN + + SRS PHASE SHIFTER 1 PHASE SHIFTER 2 5 7 I2C BUS DECODER + LATCHES MONO 6 4 MIX + MIX + 1 50K HP6 AGND CREF VREFOUT 2/11 1µ F 15nF 2.2nF 27nF 4.7nF 0.47nF 1µ F 0.1 µF 0.1µ F 1µF 0.1µ F L-OUT MONO SCL SDA...
