    Hi Lawrence,

    I reviewed the schematic and only have one general comment.

    The IN0-IN23 inputs should also have a capacitor to GND on them both for transient protection and also to stabilize the input voltage for accurate measurement.  Our ESD specification are based on a 15nF capacitor for +/-8kV protection, but the protection level will vary based on the components used.  See the TIC12400-Q1 and TIC10024-Q1 ISO-10605 ESD Test Report (Link) for additional information on the resistor and capacitor filter components.

    Let me know if you have any additional questions.

    Regards,

    Jonathan
