Hi ,

We have chosen ADE7878 and ADE7880 for Three Phase Static Energy Meter application. Evaluation guide (UG-356) and Application note(AN-1334) recommending antialiasing filters RC Value is 1K and 2.2nF for default corner frequency is 72KHz.

Is it suitable for India working frquency (50Hz), Can i use this same value? (Our meter should support IS13799 / IS15884 std.)

Please Suggest the same

 

Thanks

Rajan
