measurement results.
Notes:
MS1045-E-02
- 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 etc.
- VSS1-4 must be connected to the same analog ground plane.
- When AOUT drives a capacitive load, some resistance should be connected in series between AOUT and the
- All input pins except pull-down/pull-up pins should not be allowed to float.
