    Hi keiven,

    The HART physical layer test is a system level test of the end product (transmitter, analog input module, etc). Of course, the DAC874xH was designed to meet the HART physical layer standard, but it is not an IC level test.

    We have a transmitter reference design that uses DAC8740H which has been physical layer tested and registered as HART compliant. The design guide provides details about the physical layer testing process and design tips for ensuring compliance.
