Part Number: ADS131A04

Can you provide an Input Bandwidth vs. Data Rate specification table for the ADS131A04.

The FMOD for my application will be 1.024Mhz.

Thanks.

Hi Tony,

the input bandwidth of ADS131A04 is limited by the digital filter.
You can approximate the -3dB frequency of the digital filter using figure 46 in the ADS131A04 datasheet.
The -3dB frequency of a SINC3 filter occurs at ~0.262 x fDATA.
