6) LIN1/RIN1/LIN2/RIN2/LIN3/RIN3 → MOUT
(1) When AVDD and DVDD are supplied separately, AVDD should be powered-up after DVDD rises up to 1.6V or
(2) PMVCM bit should be changed to “1” after PDN pin goes “H”.
(3) LIN1M, LIN2M, LIN3M, RIN1M, RIN2M and RIN3M bits should be changed to “1” after PMVCM bit is changed
(4) When LIN1M, LIN2M, LIN3M, RIN1M, RIN2M or RIN3M bit is changed to “1”, LIN1, RIN1, LIN2, RIN2, LIN3
(5) PMMO bit should be changed to “1” at least 2ms (in case external capacitance at VCOM pin is 2.2μF) after LIN1M,
(6) When the PMMO bit is changed, pop noise is output from MOUT pins.

more. When AVDD and HVDD are supplied separately, AVDD should be powered-up at the same time or earlier
than HVDD. PDN pin should be set to “H” at least 150ns after power is supplied. MCKI, BICK and LRCK can be
stopped when DAC is not used.
