VDD1, VDD2, VDD3, VDD4, and VDDA must be shorted to a common source on PCB. And VREFH should always be equal to or less than VDDA + 0.1 V and VDD + 0.1 V.</P><P>So, all VDDx voltages should be equal and if VDDx is 3.3V, VREFH must not exceed 3.4V.</P><P></P><P><BR />Have a great day,<BR />TIC</P><P>-------------------------------------------------------------------------------<BR />Note:<BR />- If this post answers your question, please click the "Mark Correct" button.
