  • LDC0851: LDC0851 Suitability for Dome Switch Detection

    TI Thinks Resolved
    Part Number: LDC0851 Other Parts Discussed in Thread: , LDCCOILEVM Hello, I am looking into using an LDC0851 chip to detect a metal PCB dome's actuation (for example: GX12900 - Snaptron) . I have done some basic testing using the LDC0851EVM and LDCCOILEVM…

  • LDC0851: How to deal with radiated emissions caused by the LDC0851 circuitry?

    TI Thinks Resolved
    Part Number: LDC0851 Normally we'd use ground planes and shielded boxes to avoid failing emi tests, but neither of those approaches could work with the inductive sensor. So what are good approaches?

  • LDC0851: LDC0851 - More Coils Means Longer Detection Distance

    TI Thinks Resolved
    Part Number: LDC0851 Tool/software: Im hoping someone can help confirm or correct my intuition here. I am using an LDC0851 in an project counting the teeth on a spinning wheel. Because of the enclosure, I need the detection distance to be >6mm. Instead…

  • LDC0851: Stacked Coils

    Part Number: LDC0851 I have 8mm diameter coil. The Id is 2.4mm. The current design is 4 layers. 3mil track and 3 mil gap. 1mm thick. One thing I am not sure of is how symmetrical the coils must be from top to bottom? The layer stack: What will…

  • LDC0851: Maximum sensing distance

    TI Thinks Resolved
    Part Number: LDC0851 Other Parts Discussed in Thread: LDC1614 , LDCCOILEVM , LDC1612 , LDC1614EVM Hi, We need to design a inductive sensor using LDC0851. Kindly confirm whether this will support the maximum distance( >=45mm) between the target and the…

  • LDC0851: Target thickness requirement and reference coil requirement

    TI Thinks Resolved
    Part Number: LDC0851 Hi team Thank you for supporting. I have two questions. Do target have size and thickness reqirements? Can chip inductor use for referens coil? Best Regards Tomita
