    Hi ADI Team,
    

    

    I am looking for a current sense receiver amplifier application note, guideline, ref design for the AD5749 that is used in CN-0533 interfacing with ADXL1002
    

    to interface with AD7768 as of CN-0540 ref design.
    

    

    Any suitable amplifier part reference would be much appreciated, ideally around the ADA4945-1.
    

    

    Thanks in advance.
    

    

    Greetings,
    

    Lala

        Any feedback guys?
        

        As we moved forward with prototyping, we actually implemented a solution using AD8420 configured with a 50R load as 4-20mA current receiver and optionally also configured the ADA4945 as SE input stage with a 54R9 load resistor and calculated the FB path to amplify full scale minus some head-room. Waiting for the PCBA now to start testing.
