( Common Note)
This is value in steady condition, not the falue of peak power at the time of COM operation.
Some marging for power supply is recommended.
We recommend capacitor for VDD and VDDA.
(If VDD and VDDA are on separate systems, we recommend capacitor for each.)
Formula for computation
(Ivdd + Ivdda )[uA] × 3[V]
*LC inversion : LC material is needed alternative polarity driving as changing timing which should be 60Hz.
( LC inversion frequency 60Hz is COM frequency 30Hz)
as shown fig6-5.
