[AK4671]
■ MIC/LINE Input Selector
The AK4671 has input selector. When MDIF1, MDIF2, MDIF3 and MDIF4 bits are “0”, INL1-0 and INR1-0 bits select
LIN1/LIN2/LIN3/LIN4 and RIN1/RIN2/RIN3/RIN4, respectively. When MDIF1, MDIF2, MDIF3 and MDIF4 bits are
“1”, LIN1/RIN1, LIN2/RIN2, LIN3/RIN3 and LIN4/RIN4 pins become IN1+/−, IN2+/−, IN3+/− and IN4+/− pins,
respectively. In this case, full-differential input is available (Figure 53).
