c Balancing Network
It is possible to switch the Balancing Network between two systems, one for the near end and one for the far end, in accordance
with the line current. (Refer to Fig. 1 for the connection method.) In addition, the switching point can be varied by connecting the
PADC pin (pin 50) to GND or to S. V_CC (pin 63) via a resistor.
(When using only one Balancing Network, refer to Fig. 2.)

c The DC characteristics when the power is off
Load
LA8518NM
By connecting a load to V_SP (pin 62), it is possible to change the DC characteristics without changing the DC characteristics only
when the power is off. (Refer to the diagram below.)
