    Hi Gobinath,

    We are in the process of updating the ADS1232 datasheet which will have some layout guidelines.  In the meantime you may find the ADS1232REF user's guide helpful:  

    http://www.ti.com/lit/ug/sbau120b/sbau120b.pdf

    The ADS1232 should have a low impedance connection between the AGND and DGND of the device.  To accomplish this low impedance connection, the ADS1232REF is a 2-layer board designed with a solid ground plane (AGND and DGND combined).  For the remainder of the layout, the main goal is to keep digital signals from crossing into the analog domain on the PCB.  Other than that, there are no special requirements with respect to design rules.  For example, you could use 10mil traces and 8mil spacing.  The ADS1232REF does use 20mil analog traces, but this is not required.
