Thanks for ur replay, I have one more doubt about Barometer. In evaluation board while monitoring 32 bit Barometer data we found it to be fluctuating too much

Image of data capture

What I saw on data sheet was "barometer output registers (BAROM_xxx) update at a
rate of 51.25 SPS"(page_no-26 ADIS16480 datasheet). I made sure in evaluation board software sampling period was 2460 sps.
Theoretically barometer value should not change for in-and-around 48 samples, while capturing data since its sampling freq is 51.25 sps. But in image it has shown change from sample to sample. Why?
