Note: The absolute maximum rating is a value that must not be exceeded to guarantee the reliability and life of
this IC, and thus, the use of this IC over the rating even for a moment may break down the device
immediately or deteriorate its reliability severely.
*1: VSS covers all ground terminals including VSS, VSSL, VSSR, PVSSL and PVSSR. Place all VSS
terminals in the same potential.
*2: The voltage is referenced to VSS=0V.
*3: 12V system power supply terminal (PVDD) covers PVDDL and PVDDR terminals.
*4: 5V system power supply terminal (VDD) covers VDDL and VDDR terminals.
*5: 12V system input/output terminal covers SENSENL, SENSEPL, SENSENR, SENSEPR, HP_L, HN_L,
LP_L, LN_L, HP_R, HN_R, LP_R and LN_R terminals.
*6: 5V system input/output terminal covers SLEEP, MUTE, PROT, TPP, INL, NFINL, VREFL, NFPL, NFNL,
CDIL, CDOL, INR, NFINR, VREFR, NFPR, NFNR, CDIR and CDOR terminals.
