Part Number: LDC0851 Other Parts Discussed in Thread: LDC1612 , LDC1312 Hello guys,
I am evaluating the use of the LDC0851 sensor to count the number of turns of a hydrometer pointer to measure water. Each turn corresponds to one liter.
The problem I need…
Hello Reed,
While you check on the PCB ground planes, can you also check on what the spacing is between your layers? Specifically the spacing between your sense and reference coils (between layers 2 and 3).
Also, one other thing to consider, are there…
Part Number: LDC0851 In reference to a stack coil design; given a four layer board @0.62mils (1.5748mm) using 1oz copper for all layers; what is the recommended distance between coil layers so as to the greatest distance between the Lref and Lsense, where…
Part Number: LDC0851 Other Parts Discussed in Thread: LDC1312 , LDC1001 , LDC1101 Couple of questions around this IC or recommended replacements
Looking for experience on response times of these type of ICs. Are talking uS or Milliseconds ?
Will they…
Part Number: LDC0851 Hi
I was wondering if rather than the standard planar problem shown by many of the design references for the LDC0851, it would be possible to use this sensor in to detect the presence of a stainless steel shaft going through a hole…
Part Number: LDC0851 Hi TI Team,
how precise does the layer orientation have to be for a stacked coil? In my application I have a coil with 16 turns and a distance between the turns of 0.15mm. The copper width is also 0.15mm. Approx. every 10th circuit…
William,
Glad to hear you are seeing good performance with the EVM! Yes, the LDCCOILEVM is really intended for single coil devices like the LDC1612, LDC1101, etc. I was able to make it work with 2 of the 46mm coils, but the performance was unstable. It…
Part Number: LDC0851 Hello, I have an LDC0851EVM board with a 20mm Inductor attached.
Testing with this I only get a switching distance of about 4mm max, with a large amount of aluminium as teh target, basedon the datasheet I was expecting a bit more…
