I have a question about the antialiasing filter of ADE7880.
In the evaluation board of ADE7880, the attenuation network is used to the voltage sense inputs.
The network is low-pass filter with a corner frequency of 72KHz.
In the data sheet of ADE7880, it is recommended that the RC filter with a corner frequency of 5KHz be used.
Should I design the attenuation network with the corner frequency of 5KHz?
Or, should I add the RC filter with the corner frequency of 5KHz to the attenuation network of the same value as the evaluation board?
