ASAHI KASEI
The common voltage is 0.475 x AVDD. The load resistance is 10kΩ(min). When the PMLO bit is “1”, the stereo line
output is powered-up. DACL, LINL, MINL, DACR, RINR and MINR bits set the path, respectively. When LOG bit is
“0”(R
the DAC path gain is +6dB.
LOUT/ROUT volume is controlled by ATTS3-0 bits when LMUTE bit = “0” (0dB ∼ −30dB, 2dB step, Table 24). Pop
noise occurs when ATTS3-0 bits are changed.
