LDC0851: LDC0851 drift

Iwata Etsuji

Part Number: LDC0851

Hi team,

In the displacement application, some temp drift of target distance threshold is seen with LDC0851 and fixed SENSE/REF coil.
It could cause some threshold error/variation (up to several %).

Could you please clarify the device variation in regard to temp drift?

While, if you could suggest how we could improve the system level temp drift, it should be appreciated.

Best regards,

Hi Etsuji-san,

Because the detection threshold depends heavily upon system variables, we cannot characterize it over temperature at a device level. Could you share more details about your customer's system? Hopefully we can find a way to improve the temperature drift.

Could you clarify what temperature range the customer is testing?

Best Regards,

Hello Etsuji-san,

I haven't heard from you, so I'm assuming you were able to resolve your question. If this is not the case please feel free to post a new question.

Best Regards,
