  • LDC1614: Jumps in output values

    Resolved
    Part Number: LDC1614 Hi, I’ m experiment ing with a LDC1614 on a custom board with a PCB coil. While it generally works fine, I get jumps in the output signal when moving towards and away from the target. To have precise movement I mounted the…

    Hello Amy, Can you share any diagram/drawing of the coil and the nearby metal that you are trying to shield from? Thank you, Justin Beigel

  • LDC1614: Frequency setting, Settling time of the oscillating circuit & Setting IDRIVE current

    Part Number: LDC1614 Hi Team, Can you have a look at the following customer inquiry, please? Frequency setting: It must be possible to divide the frequency range (15 kHz to 150 kHz) into 5 to 6 frequency ranges. The data sheet states that the digital output…

  • LDC1614: The differences between the four channels

    TI Thinks Resolved
    Part Number: LDC1614 LDC1614 has four measurement channels. In the process of testing, it was found that channel 0 was relatively stable. I would like to ask if there are differences in stability, sensitivity and accuracy among the four channels?

  • LDC1614: I2C gaps between register readings and repeated start to access additional registers

    Resolved
    Part Number: LDC1614 Hello, 1) Looking at the I2C communication on the evaluation board LDC1614EVM shows a ~16us gap between the Register 0x00 (DATA0_MSB) and Register 0x01 (DATA0_LSB) readings. Is this a limitation of the LDC1614EVM since the LDC1614…

    Hi Sayali, Unfortunately, most of our reference designs, like the one you have shared a link to, are not available for sale. We do however, include design files that you may reference if you would like to build it yourself. The firmware that you downloaded…

  • RE: LDC1614: Inductance value increased with time

    Hello Jonathan, We do not have their coil design here to test with but one step we can do to get a better understanding is to look at the sensor oscillation with an oscilloscope. The LDC1614 operates on a discontinuous sine wave driver so it will be best…
