(1) Set LOPS bit = “1”. Stereo line output enters the power-save mode.
(2) Set PMLO bit = “1”. Stereo line output exits the power-down mode.
LOUT and ROUT pins rise up to VCOM voltage. Rise time is 200ms (max 300ms) at C=1
μ
F and
AVDD=3.3V.
(3) Set LOPS bit = “0” after LOUT and ROUT pins rise up. Stereo line output exits the power-save mode.
Stereo line output is enabled.
(4) Set LOPS bit = “1”. Stereo line output enters power-save mode.
(5) Set PMLO bit = “0”. Stereo line output enters power-down mode.
LOUT and ROUT pins fall down to AVSS. Fall time is 200ms (max 300ms) at C=1
μ
F and AVDD=3.3V.
(6) Set LOPS bit = “0” after LOUT and ROUT pins fall down. Stereo line output exits the power-save mode.
