Note: Please refer to “explanation of register” about the condition of each register.

(1) Digital output corresponding to analog input and analog output corresponding to digital input have the group

(2) If the analog signal does not be input, the digital outputs have the op-amp of input and some noise in ADC.

(3) ADC data is “0” data at power-down.

(4) A few noise occurs at the “

(5) When the external clocks are stopped, the AK4563A should be in the power-down mode (PDN pin = “L” or
