[AK4516A]
• INIT: Initializing. At this time, ZFIPL and ZFIPR are "0". When these flags becomes "1", INIT
process has completed.
• PD:
Power-down state. ADC is output "0", analog output of DAC goes floating.
• INIT-1: Initializing all registers.
• INIT-2: Initializing read only registers in control registers.
• Inhibit-1: Inhibits writing and reading to all control registers.
• Inhibit-2: Enable writing to control registers except "Mode Control 1 (01H)" register.
• Inhibit-3: Enable reading from control registers.
• Inhibit-4: Enable writing to only "Mode Control 1 (01H)" register of the control registers.
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 delay(GD).
{2 If the analog signal does not be input, the digital outputs have the offset to the op-amp of input and some
offset error of the internal ADC.
{3 A few noise occurs at the "↓↑" of PD signal.
Please mute the analog output externally if the noise influences the system application.
{4 When the external clocks are stopped, the AK4516A should be in the power-down mode.
