[AK4679]
■ MIC/LINE Input Selector
The AK4679 has input selector. When MDIF1, MDIF2 and MDIF3 bits are “0”, INL1-0 and INR1-0 bits select
LIN1/LIN2/LIN3/LIN4 and RIN1/RIN2/RIN3/RIN4, respectively. When MDIF1, MDIF2 and MDIF3 bits are “1”,
LIN1/RIN1, LIN2/RIN2 and LIN3/RIN3 pins become IN1+/−, IN2−/+ and IN3+/− pins, respectively. In this case,
full-differential input is available (Figure 54). Digital microphone input is selected when DMIC bit = “1”.
