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.

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.

Both power supply and +power supply are +VCC.
