38 / 156 page ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 26 Rev. 0.93 7.6.2. 4 DACs with 4-Channel Playback Path There are four analog DACs and with up to 4-channel playback path. Two I2S interfaces provide four channels data to analog DACs. And analog DAC can output audio signal to speaker output, headphone output, mono output or line output. The full scale output of analog DAC is around 1Vrms at line output port. In order to save power, the four analog DACs can be powered down separately by setting pow_dac_l_1 (MX-61[12]), pow_dac_r_1 (MX-61[11]), pow_dac_l_2 (MX-61[7]) and pow_dac_r_2 (MX-61[6]). And the digital volume control of the four DACs are also separately controlled by vol_dac1_l (MX-19[15:8]), vol_dac1_r (MX-19[7:0]), vol_mono_dacl (MX-1A[15:8] and vol_mono_dacr (MX-1A[7:0]).
