Note 1) VSS means AVSS, VSSBGR, DVSS, PVSSR, and PVSSL. Keep all the VSS terminals at the same potential.

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

Note 3) The power supply terminal (VDDP) means PVDDREG, PVDDR, and PVDDL terminal.

Note 4) The control input/output terminal means MUTEN, MONO, GAIN[2:0], MODE[1:0], BITSEL, FSSEL, SCLK, LRCLK, and SDIN terminal.

Note 5) The input/output terminal means VREF and GAINA terminal.

Note 6) Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability and life, and when using a device in excess

even a moment, it may immediately cause damage to device or may significantly deteriorate its reliability.
