The analog filter in the front-end is limited to a bandwidth of 200 kHz. You can use the filter wizard ( wiki.analog.com/.../filters ) to program the programmable FIR to arrive at an overall filter response that is narrower. But, note that the minimum sample rate is limited to 520.83 KSPS, since the minimum ADC rate is 25 MSPS and the overall max decimation is 48.
