If you are just getting started with inductive sensing, the following may be useful for understanding how the technology works:

Hello Hirata,
We have seen this behavior before, and it is most likely due to environmental factors. For button-press applications, we recommend using a baseline tracking algorithm. The design guide for TIDA-01102 discusses this algorithm.
Best Regards…
Hello Will,
Connecting multiple channels together like this will cause the LC tank on other channels to become part of the measurement. Even using multiple FDC chips, you would still see this happen since other channels LC tanks will be connected. You…
Part Number: LDC1614 Other Parts Discussed in Thread: TIDA-01102 Hi Team, TIDA-01102 shows the following Table 5. http://www.ti.com/lit/ug/tiducr1/tiducr1.pdf 1) I believe "Sensor coil inductance (free space)" can be estimated by Webench Coil Designer…
Hi Dan, i recommend looking at TI reference design TIDA-01102 ( www.ti.com/.../tiducr1.pdf) they use TS3A5017 as multiplexer there. Kind regards, Clemens
Jianeng,
As you have seen in the posts, the LDC devices use an inductive sensor and a component capacitor to form a resonant LC circuit.. The LDC device monitors the LC sensor waveform, counts its axis crossings and then compares that to a reference…
Hello,
The inductive sensing devices can only detect metal targets. If a conductive layer (such as copper or aluminum tape) can be applied under the glass, then this could work for inductive sensing. Please note that the glass will need to deflect under…
1. You should be able to mux the FDC1004 as long as you aren't using the repeat mode of operation. You will need to manually trigger each measurement. We haven't evaluated this option, so I do not have a specific mux to recommend.
2. The FDC2214 can…
Hi Vincenzo,
To use inductive sensing for this application, the customer would need to have a metal target. They could possibly add metal to the back of their glass keypad, but I'm not sure that the glass will be elastic enough to create a functional…
This is a very good and question and something most people really don’t think about. Appliances are something we interact with on a regular basis, and sensors can help improve the quality of our interactions with our devices. Sensors allow our appliances…
