Figure 27. Typical Connection Diagram
Note:
-
A 2
resistor must be added in series between HVDD pin and power supply line in order to
limit the current.
These capacitors at CP/CN pins and HVSS/NVSS pins require low ESR (Equivalent Series Resistance) over all
temperature range. When these capacitors are not bipolar, the positive side should be connected to CP pin and
HVSS respectively.
AVSS, DVSS and HVSS of the AK4665A should be distributed separately from the ground of external
controllers.
All digital input should not be left floating.
