Hi all,
I am using ADE7758 Energy meter Ic. In IC datasheet they given Typical Application Circuit Diagram. i followed that correctly. In current channel section, am giving the CT Input ,wave comes correctly(220mV, VPP) while checking the CRO. But when i am connecting the Netural to the IC ground. wave form not comes purely. that time peak to peak voltage goes 2.3V,VPP. Without neutral connecting time it come correctly.
please suggest me,if any changes in the circuit PDFwhich i attached.
