    Hello everyone
    I have made an load sensing circuit using an instrumentation amplifier AD620. The sensor I have used is a typical load cell which is powered using +-5volt power supply. The Power supply i am using is Net35b meanwell power supply.(snippet from the datasheet)

    QUESTION
    Do i need to design a filter for output stability? If yes how should i do it ??.

    Thank you in advance !

    That depends on the rest of your circuit, but unless you are measuring the supply rails to compensate for their changes, the accuracy of your measurement will not be better than the 2% accuracy of the supply that powers the load cell.
