Notes:
Figure 73. Typical Connection Diagram (AIN3 bit = “1”: PLL is not available, RCV bit = “1”, Line Input)
- AVSS, DVSS and HVSS of the AK4343 should be distributed separately from the ground of external
- All digital input pins should not be left floating.
- When AIN3 bit = “1”, PLL is not available.
- When piezo speaker is used, 2.6 ∼ 5.25V power should be supplied to HVDD and 10Ω or more series resistors
controllers.
should be connected to both SPP and SPN pins, respectively.
