• Manufacturer Part Number: AK5702VN
• Description: 4-Channel ADC with PLL & MIC-AMP
• Manufacturer: AKM [Asahi Kasei Microsystems]

■
The AK5702 has input selector. When MDIF1 and MDIF2 bits are “0”, INAL and INAR bits select LIN1/LIN2 and
RIN1/RIN2, INBL and INBR bits select LIN3/LIN4 and RIN3/RIN4 respectively. INA5L and INA5R bits also select
LIN5 and RIN5, respectively. Refer to Table 24 about the typical input resistance of LIN5, RIN5. When MDIF1 and
MDIF2 bits are “1”, LIN1, RIN1, LIN2 and RIN2 pins become LINA+, LINA−, RINA− and RINA+ pins, LIN3, RIN3,
LIN4 and RIN4 pins become LINB+, LINB−, RINB− and RINB+ pins respectively. In this case, full-differential input is
available (Figure 40).
