  • FDC2214: FDC2214

    Resolved
    Part Number: FDC2214 Other Parts Discussed in Thread: FDC1004 We are working on a capacitive sensing application that has 8 separate capacitive inputs. We are using the 4-channel FDC2214 to sense these elements. PCB space is very tight in this design…

  • FDC2214: Data in all conversion result registers are not updated automatically

    TI Thinks Resolved
    Part Number: FDC2214 Other Parts Discussed in Thread: CC2650STK , , CC2650 Dear TI experts, I am using cc2650stk to read data from 0x00 and 0x01 of a custom FDC2214 board via I2C. Yesterday, variable data could be continuously read from the conversion…

  • RE: FDC2214: How to design sensor for anti-collision application

    Hello John, We don't have any tools for sensor design, but you can use something like FEMM to simulate the electromagnetic fields of the sensor. There is documentation on the tool on their homepage and we also have an app note discussing how to Simulate…

  • FDC2214: Can customer use one electrode for liquid level detection?

    TI Thinks Resolved
    Part Number: FDC2214 Other Parts Discussed in Thread: FDC1004 Hi team, In the typical application of FDC2214, three electrodes are used. Customer want to know if they can only use one level sensor to realize the liquid level detection? Do you have any…
