5 / 9 page LA6559 No.A0597-5/9 Pin Functions Pin No. Symbol Pin descriptions 1 REV 5CH (VLO) Output change pin (REV), logic input for loading block. 2 S-VCC Signal system power supply (BTL-AMP : CH1 to 4) 3 VCC2 Power supply for loading block 4 VLO- Loading output (-) 5 VLO+ Loading output (+) 6 VO4+ Output pin (+) for channel 4 7 VO4- Output pin (-) for channel 4 8 VO3+ Output pin (+) for channel 3 9 VO3- Output pin (-) for channel 3 10 VO2+ Output pin (+) for channel 2 11 VO2- Output pin (-) for channel 2 12 VO1+ Output pin (+) for channel 1 13 VO1- Output pin (-) for channel 1 14 VCC1 CH1 to CH4 (BTL-AMP) output stage power supply 15 VIN1 Input pin for channel 1 16 VIN1- OP-AMP input AMP-A input pin (-) 17 VIN1+ OP-AMP input AMP-A input pin (+) 18 VIN2 Input pin for channel 2, input AMP output 19 VIN2- Input pin (-) for channel 2 20 VIN2+ Input pin (+) for channel 2 21 VCC-VREG 3.3VREG power supply 22 GND-VREG 3.3VREG GND 23 VIN3 Input pin for channel 3, input AMP output 24 VIN3- Input pin (-) for channel 3 25 VIN3+ Input pin (+) for channel 3 26 REG-IN PNP transistor base connected 27 REG-OUT 3.3V power output to which the PNP transistor collector connected. 28 VCONT (LOADING) Output voltage set pin for loading block 29 VREF-IN Reference voltage applied pin 30 VIN4+ Input pin (+) for channel 4 31 VIN4- Input pin (-) for channel 4 32 VIN4 Input pin for channel 4, input AMP output 33 MUTE1 Output ON/OFF, channel 1 (BTL AMP) 34 MUTE2 Output ON/OFF, channel 2 to 4 (BTL AMP) 35 S-GND Signal system GND 36 FWD Output change pin (FWD) for loading output (VLO+ -), logic input for loading block. Note 1 : Center frame (FR) becomes GND for the power system (P-GND). Set this to the minimum potential together with S-GND. Note 2 : Short-circuit each of VCC1, VCC2, VCC-VREG, and S-VCC power pins externally. |
