4 C1N passive Negative flying capacitor connection; connect a 1µF capacitor between C1P and C1N.
5 PVSS power_out Negative charge-pump output; bypass to PGND with 1µF.
6 SGND power_in Signal ground; connect PGND and SGND together at the system ground plane.
7 INR+ input Right positive polarity input.
8 INR- input Right negative polarity input.
9 SVDD2 power_in Signal path power-supply input; bypass to PGND with 1µF and connect directly to PVDD.
10 OUTR output Right DirectDrive output.
11 BIAS passive Internal supply node; bypass to PGND with 0.1µF and do not connect external loads to it.
12 OUTL output Left DirectDrive output.
13 SVDD power_in Signal path power-supply input; bypass to PGND with 1µF and connect directly to PVDD.
14 INL- input Left negative polarity input.
