Hi Forum Members,

    Hi Saravanan,

    Have you enabled both the LVDT loopback connection in LVDT_LPBK_CTRL, and also the loopback amplifier itself in the DAC_LPBK_CTRL register? It can be easy to miss the LB_AMP_EN bit if you only intend to use the LVDT loopback, since it is in a separate register. Please make sure LB_AMP_EN is also set to 1.


    Regards,
    Scott
