Hello Vikas, We would recommend to use an I2C multiplexer for communication to the different FDC devices. We have test before the ability to dynamically change the I2C address pin and it does seem to work, but this is not documented in the datasheet so…
Hello Kiran,
Inductive sensing can be used for both rotary switch applications and push button switch applications. I would recommend to take a look at our design collateral:

Part Number: LDC1314 Other Parts Discussed in Thread: LDC1614 , TIDA-00509 , LDC1101 , TS3USB30E Hi,
I'm developing a inductive sensor using LDC1314.
The sensor should be able to detect a coin type metal (10mm minimum diameter, steel, 2mm thickness)…
Hi Ron,
a recommended approach for measuring multiple sensors is using the multi-channel LDC devices:
LDC1612/1614 (high resolution) or
LDC1312/1314 (mid resolution)
They exhibit excellent channel-to-channel matching and many improvements over the LDC1000…
Hello,
If you are looking at detecting the pressure applied to a metal surface then I would direct you to the following collateral:

Dear Technical SUpprot Team,
I have a question about FDC2xxx.
Can FDC2xxx use analog mux for multicahnnel interface?
LDC can use multi channel with analog mux like following 16-button KeyPad.

Hello swu,
1. Generally yes, but without reviewing a design drawing it is difficult to determine. It is important to consider both the maximum sensing range and the ratio of target size to sensor size: https://e2e.ti.com/blogs_/b/analogwire/archive/2015…
Hi Geoffrey:
It is possible to use external multiplexers. When it mentions that it does not support hot-swapping, that means, that the device cannot be driving the waveform when the multiplexers are switched. If that happens, the device could get damaged…
