Hello,

 

I have some questions about ADC of the ADE7880.

 

Q1:

The gain error of ADC is written ±4%(typ) in the datasheet.

(Test Conditions : PGA =1)

Does the error of PGA contain in the gain error?

Does the value of the gain error change depending on the condition of PGA?

(PGA = 4, 8, 16)

 

Q2:

When internal HPF is connected, can the offset error of ADC be ignore?

 

Best Regards,

Mr.K
