Note:
1. Grounding and Power Supply Decoupling
The AK4125 requires careful attention to power supply and grounding arrangements. Alternatively if AVDD and DVDD
are supplied separately, the power up sequence is not important. Decoupling capacitors should be as near to the AK4125 as
possible, with the small value ceramic capacitor being the nearest.
MS0379-E-05
• Input PORT: Slave Mode, IBICK lock mode (64fsi), 24bit MSB justified
• Output PORT: Master mode, 24bit MSB justified
• Dither = OFF
- AVSS and DVSS of the AK4125 should be distributed separately from the ground of external digital
- All digital input pins should not be left floating.
