SUMMARY OF FILTER OPTIONS
The AD7193 has several filter options. The filter that is chosen
affects the output data rate, settling time, the rms noise, and the
50 Hz/60 Hz rejection.
Table 36 shows some sample configurations and the corresponding
performance in terms of throughput, settling time, and 50 Hz/
60 Hz rejection.

These calculations assume a 4.92 MHz stable master clock.
2
Throughput is the rate at which conversions are available when several channels are enabled. In zero latency mode, the output data rate and throughput are equal.
3
For fast settling mode, the 50 Hz/60 Hz rejection is measured in a band of ±0.5 Hz around 50 Hz and/or 60 Hz. For all other modes, a region of ±1 Hz around 50 Hz
and/or 60 Hz is used.
4
For output dates rates greater than 1 kHz, the sinc4 filter is recommended.
