Figure 7 and 8 show the system connection diagram. An evaluation board [AKD5394A] is available which demonstrates
the optimum layout, power supply arrangements and measurement results.
MS0137-E-03
Notes:
System Ground
- LRCK = fs, SCLK = 64fs.
- Power lines of VA and VD should be distributed separately from the point with low impedance of regulator etc.
- AGND, BGND and DGND must be connected to the same analog ground plane.
- All digital input pins should not be left floating.
- Refer Table 4 and Figure 12 about C.
