ADS1281 FIR coefficients

Other Parts Discussed in Thread: ADS1281

Hi,


In the ADS1281 datasheets appendix, there is a table referring to "session 1,2,3,4" and "scaling" 1/512, 1/8388608 and 134217728. Where do these numbers come from?

I need to know the FIR coefficients for each of the 3 FIR stages. I understand it changes when you select linear phase response or group phase response. But what other register setting affect the FIR coefficients? How is it related to the table in Appendix A?

Thanks,

Yoram
