Similarly when a condenser is input at the position between pin 3 (DCCNT2) and GND, it becomes the mode with 0.3V DC offset between input and output of 1, 2, 3ch (pins 7 and 34, pins 9 and 29, pins 11 and 27), and when a condenser is input at the position between pin 17 (DCCNT3) and GND, it becomes the mode with 0.3V DC offset between input and output of 4ch (pins 13 or 15, and pin 31). And when pins 1, 3, 17 and GND is shorted, it becomes the mode without DC offset between input and output. 2 GND Both ±power supply and +power supply are GND. 4 18 32 5 7 9 11 VIN1A VIN1B VIN2 VIN3 15 VIN4A VIN4B 6 NC 13 Input terminal.

VOUT4 VOUT3 Output terminal VOUT2 VOUT1 possible to use without capacitor of output by setting Equivalent Circuit 21 25 27 29 34 Using ±power supply, in case of the mode with DC offset, it is pin 5 to 0.6V-bias and by setting pins 7, 9, 11, 13, 15 to 0.3V-bias. And in case of the mode without DC offset, it is possible to use without capacitor of output by setting each input to zero-bias. When using +power supply, both of the modes needs coupling capacitor. 36 +VCC Both ±power supply and +power supply are +VCC.
