I apologize that the documentation doesn’t cover this in more detail. Here are the minimum bandwidths that can be selected based on decimation.
[1 -> 128] : 50kHz
 : 20kHz
 : 10kHz
 : 5kHz
 : 2kHz
 : 1kHz
 : 0.5kHz
These are absolute minimums and be aware that they are chosen as the practical limit based on the internal sample rate and FIR filter size used. I recommend specifying your own limits that are realistic to your application and using a combination of bandwidth and sample rate to achieve your necessary streaming requirements.
If you have any further questions, please let me know.
