Figure 32. Typical Connection Diagram in 3-wire mode
Note:
-
A 2
resistor should be added in series between HVDD/PVDD pins and power supply line in
order to limit the current.
These capacitors should use low ESR (Equivalent Series Resistance) over all temperature range. When these
capacitors are not bipolar, the positive side should be connected CP pin or analog ground.
AVSS, DVSS, PVSS and HVSS of the AK4342 should be distributed separately from the ground of external
controllers.
All digital input except for pull-up pins should not be left floating.
If TVDD voltage is the same as DVDD voltage, TVDD pin is directly connected to DVDD pin and the capacitor
(10
μ
F and 0.1
μ
F) connected to TVDD pin can be removed.
