Figure 17 and Figure 18 show the system connection diagram. The evaluation board demonstrates application circuits, the
optimum layout, power supply arrangements and measurement results.
TBD
Note:
- AVSS, BVSS and DVSS of the AK5388 should be distributed separately from the ground of external digital
devices (MPU, DSP etc.).
- All input pins except pull-down (CKS0, CKS1 and TEST pin) pin should not be left floating.
