4) LIN/RIN/MIN → Lineout
(1) PDN pin should be set to “H” at least 150ns after power is supplied. MCKI, BICK and LRCK can be stopped when
(2) PMVCM bit should be changed to “1” after PDN pin goes “H”.
(3) LINL, MINL, RINR and MINR bits should be changed to “1” after PMVCM bit is changed to “1”.
(4) When LINL, MINL, RINR or MINR bit is changed to “1”, LIN, RIN or MIN pin is biased to 0.475 x AVDD.
(5) When the 3D function is used, 3D1-0 bits should be changed to “01”, “10” or “11” after LINL, MINL, RINR and
(6) When the 3D function is not used, MUTEN and PMLO bits should be changed to “1” at least 2ms (in case external
(7) When the PMLO bit is changed, pop noise is output from LOUT/ROUT pins.

DAC is not used.
MINR bits are changed to “1”.(refer to Table 25)
capacitance at VCOM pin is 2.2µF) after LINL, MINL, RINR and MINR bits are changed to “1”. When the 3D
function is used, MUTEN and PMLO bits should be changed to “1” at least 50ms after 3D1-0 bits are changed to
“01”, “10” or “11”.
