    MIchael, hello and thank you for your continued interest in Texas Instruments. Your query has been forwarded to the design owner (Anbu Mani, who has helped you on previous E2E questions) on our Industrial Test and Measurement team. Please allow him until Monday Bangalore time to provide a response here.

    Hi Michel Ma,

    Thanks for mail . The power layer cut and GND cut are done to prevent digital noise coupling to analog supply.
