Hi everybody )
Could someone tell me about RMS calculation width (i.e. window)? I can't find any mentions about N from expression 10 (please see AD7878 datasheet). Of course, table 13 tells that the settling time is 440 ms (for 50 Hz without integrator) but I think that it isn't really width.
Thanks
