Materials with high conductivity for inductive sensing may be expensive, so limiting the amount of material used for a target in an inductive system is of paramount importance, but what is the ideal target thickness for inductive sensing?
Kwon,
The combination of small inductors and larger capacitors can present a challenge.
Attached is a document that might help. It was once a blog post about using small inductors, but has been since taken down (don't know why).
Please look it over…
In order to understand what materials works best for inductive sensing we first must understand how inductive sensors work. Inductive sensors are designed to detect metal targets through the use of eddy currents. When the conductive target interacts with…
Susmitha,
Thank you for your post and your interest in the LDC1612.
There are a couple of resources you can leverage.
The E2E Inductive sensing FAQ has a wealth of information on using our inductive sensors.
The Inductive Sensing Design Calculator…
Hello Marko,
Glad you have found the evaluation kit helpful. Presently both of our inductive sensing experts are out on leave. However, one of them will be returning next Tuesday. Would a discussion with him then be ok?
Part Number: LDC0851 Tool/software: Hello community, I'm looking for the following blog post, which is also referred to in TI's application report SNOA930C "Sensor Design for Inductive Sensing Applications Using LDC":

Gary,
I don't have any calculations to offer that allow computing the column #Unique Codes. There are too many dependencies on the device settings and on the sensor parameters to be accurately captured in a simple model or calculator. This is an active…
Kailyn,
I believe you could use the LDC1614 for open/close detection as shown in the blog. One possible example would be using channel 1 as the sense coil while channel 2 could the reference coil. Unlike the LDC0851, you will need a uC to manage the…
Part Number: LDC1612 The part LDC1612DNTT shows a typical temperature coefficient of -13 ppm/deg C.
Are you able to give a maximum value that we can use for design purposes?
We are currently using an external oscillator with good specs. To lower the…
Hello,
We have the Power Reduction Techniques for the LDC131x/161x for Inductive Sensing app note describing how to use the LDC1612 by waking it up to take measurements. You will have to manually sleep and wake up the LDC1612. For built in low power…
