- Power lines of AVDD and DVDD should be distributed separately from the point with low impedance of regulator
- VSS1/2/3/4 must be connected to the same analog ground plane.
- When AOUT drives a capacitive load, some resistance should be added in series between AOUT and the
- All input pins except pull-down/pull-up pins should not be allowed to float.
