Figure 27. AUX Input
AUX input is differential input at AUXSI bit = “0” and single end input at AUXSI bit = “1”. AUXIN+ pin should be used
at single end input (AUXSI bit = “1”). The AK4641 has a volume for AUX Input. This Volume is controlled by GN3-0
bits as shown in Table 16. The switching noise occurs when GN3-0 bits are changed.
