Notes:
etc.
MS0336-E-00
- TTL pin (BVSS pin in case of AK4394/5) should be open.
- Chip Address = “00”, BICK = 64fs, LRCK = fs.
- Power lines of AVDD and DVDD should be distributed separately from the point with low impedance of regulator
- AVSS and DVSS must be connected to the same analog ground plane.
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and
- All input pins except pull-down/pull-up pins should not be left floating.
