I am having trouble with your LDC1612, could someone please explain why I would be receiving F0FFFFFFF from the device?

Thanks

    Hello Johan,

    Please clarify - are you getting 0xFFFFFFF as the output (that is 7 Fs - corresponding to full scale)?

    The output of 0xFFFFFFF generally an error condition. You can refer to the app-note www.ti.com/.../snoa959.pdf for more information.

    This can also be caused by the reference frequency being lower than the sensor frequency, which is not a valid operating condition for the LDC1612. If Fsensor and FReference are both valid, you can use the Fin divider to compensate for that condition.
