Part Number: ADS1263
Need help setting registers for this device. There are supposed to be 5 registers to set but we only see 4 so we can't get the conversion rate as high as we need it.

Our ADS1263 experts are on holiday, returning to the office on Monday the 8th. In the meantime, can you let us know what conversion rate you are trying to achieve with the ADS1263?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Tom Hendrick:
Per table 9 on page 49 of the datasheet, 38400 but we need to access SINC5 to do this but we only see SINC1-4 in the control registers. How do we access SINC5?
In table 43 on page 92 there is no SINC5...
In reply to Kenneth Wood:
The ADS1263 datasheet is not very clear on how to select the SINC5 filter; however, the selection of the SINC5 filter happens when you program the DR register field to any of the SNIC5 filter data rates (14.4k, 19.2k, or 38.4k).
When any of these data rates are selected, the second stage SINCn filter is bypassed and the FILTER register setting (which normally controls the second stage filter order) has no effect.
I hope that helps... Let me know if you still have issues achieving the 38.4 kSPS data rate.
