Note 1) VSS means VSSL, VSSR, VSSPL1, VSSPL2, VSSPR1, and VSSPR2. Place all VSS terminals in the same potential.

Note 2) The voltage is based on VSS=0V.

Note 3) VDD terminal means VDDL, VDDR, VDDPL, and VDDPR.

Note 4) Input/output terminal means /SLEEP, /MUTE, /PROT, HP, /MONO, INL, VPL, VREFL, INR, VPR, and VREFR.

Note 5) Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability and life, and when using device in

excess even a moment, it may cause damage to device or deteriorate its reliability severely.
