TIDA-00508 accuracy if the LDC1314　changes LDC161x　28bit resolution

Other Parts Discussed in Thread: TIDA-00508, LDC1314, LDC1614

Dear Technical Support Team,

I have a question about TIDA-00508.

1º Dial demo has 0.1º resolution using LDC1314, so GUI shows xxx.1°.

If it is exchanged LDC161x(28bit resolution), how is the resolution for dial theoretically? (For example, 0.01° or 0.001°)

Customer's application is industrial, so they are interested in how the accuracy is using LDC161x.

Best Regards,

y.i

    Hello,

    For TIDA-00508, there are three main limitations - the LDC sensing element, the calibration, and the mechanical alignment. Much of the limitation of TIDA-00508 is due to the limits of the calibration and the mechanical configurations, and so you may not get a significant improvement in accuracy if the LDC1614 is used instead, unless you also significantly improve the mechanical alignment and positioning.

    As for increasing the resolution, you will need increase the programmed reference count of the LDC1614, which will lower the sample rate.

    Hi Chris,
    May I know how can to improve the mechanical alignment and positioning then improvement accuracy to 0.01° when using LDC1614?
    Thanks your suggestion.

    Best Regards,

    Hello Eric,

    Optimizing the mechanical alignment and positioning will probably require a Mechanical Engineer with expertise in your system design and your requirements.
