We are evaluating LDC1000 as roration angle detector.

The EVM provide a sample figure like vortex. Could you tell us a detailed info for this figure to get fine linearlity?

The caluculation formula is fine for us.

Hello Keiichi,

I apologize for the delay. For questions regarding LDC1000, please post to to: Sensor Products -> Inductive Sensing. Otherwise, there is no visibility of your post for me. Does the diagram below represent what you are trying to do?

Best Regrds,

Natallia,

Thank you for your reply.

What we want to do is getting linear value of rotation angle.

+-45 degree is enough, so we do not mind defective part.

Can you provide calculation formula of figure to get fine linearity?

The images is below.

Hello Keiichi,

Unfortunately we do not have an application note available on this topic. Perhaps you could create a lookup table based on your data and interpolate the later in software.

Best Regards,
