Pin Functions
Pin No. 1 3 17 Pin Name DCCNT1 DCCNT2 DCCNT3 Terminal Explanation DC offset mode charge terminal between input and output. When a condenser is input at the position between pin 1 (DCCNT1) and GND, the operation of IC becomes the mode with 0.6V DC offset between input and output of 1ch (pins 5 and 34). 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 4 18 32 5 7 9 11 13 15 VIN1A VIN1B VIN2 VIN3 VIN4A VIN4B Input terminal. Non-bias. It is possible to use with being directly connected with DC. When DC coupling, it is necessary to add bias after the coupling. GND Both power supply and +power supply are GND. Equivalent Circuit

Continued from preceding page. Pin No. 19 21 25 27 29 34 VOUT4 VOUT3 VOUT2 VOUT1 Output terminal Using power supply, in case of the mode with DC offset, it is possible to use without capacitor of output by setting 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. Pin Name -VCC. Terminal Explanation -VCC of using power supply. Using +power supply, it is GND. Equivalent Circuit
