Notes:
- AVSS and HVSS of the AK4645 should be distributed separately from the ground of external controllers.
- All digital input pins should not be left floating.
- When AIN3 bit = “1”, PLL is not available.
- When the AK4645 is used at master mode, LRCK and BICK pins are floating before M/S bit is changed to “1”.
Therefore, 100kΩ around pull-up resistor should be connected to LRCK and BICK pins of the AK4645.
