TYPICAL APPLICATIONS
Connection Guidelines
Decoupling capacitors of approximately 10 µF should be connected from AVDD, VRL, VRR to AVSS, and
from DVDD to DVSS.
In addition, approximately 0.01 µF capacitors should also be connected from AVDD, VRL, VRR to AVSS, and
from DVDD to DVSS to suppress digital switch noise.
An approximately 0.001 µF capacitor connected from RSTN to DVSS will force a system reset when power is
applied.

Connection 2
When there is a possibility that the input peak-to-peak amplitude will exceed the supply voltage, input protec-
tion diodes should be connected to prevent device breakdown.
