Notes:
- VSS1, VSS2, and VSS3 of the AK4648 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 AK4648 is used in master mode, LRCK and BICK pins are floating before M/S bit is changed to “1”.
Therefore, 100k
Ω
around pull-up resistor should be connected to LRCK and BICK pins of the AK4648.
- When DVDD is supplied from AVDD via 10
Ω
resistor, a capacitor should be 0.1
μ
F or less.
