On pg 39 of the AD7134 datasheet, the digital filter options are listed in Table 19. The second row is the "Sinc3 Filter with 50 Hz/60 Hz Rejection" filter option. In the ODR range column, the range is listed from 10 Hz to 1496 kHz. Assuming the main purpose of this filter option is to reject 50 & 60 Hz, does it make sense to include any ODR other than 10 or 50 sps in the ODR range? Based on the description of this filter option on pg 40, I suspect this filter response will have first nulls at ODR & 6/5*ODR. 50Hz and 60Hz will only be rejected if the ODR is 50 sps (or if ODR is 10 sps). Anyway, I'm just speculating. I see the same verbage in the AD4134 datasheet. Could you review and comment on this? Are the first filter response nulls at ODR & 6/5*ODR for this filter?
