Part Number: FDC2112 Hello
We are using the FDC2112 in a liquid level application. We are using a differential measurement, 2 plates inside a vessel and they have direct contact with the liquid, and the device and application is working.
However,…
Part Number: FDC1004 Other Parts Discussed in Thread: FDC2214EVM How mesure thickness for detect gap on roll of clear label. I would like know the best IC to make this and how make or where found a low cost sensor.
label gap = 3mm
backing thickness…
Part Number: FDC2112 Other Parts Discussed in Thread: FDC2212-Q1 , FDC2214-Q1 , , FDC2114-Q1 Hi everybody,
Could you please tell me what is difference between FDC2112-Q1, FDC2114-Q1, FDC2212-Q1 and FDC2214-Q1 beyond maximum output rates?
Thank yo…
Part Number: FDC2112 Critical to this devices use as a sensor over automotive temperature ranges is a temperature stable inductor. Shielded inductors are recommended for your design on the datasheet. Temperature stability information of shielded SMD inductors…
Part Number: FDC2112 Hello;
I use FDC2112 to measure capacitor with single ended mode. I read data from fdc and calculate frequency value. Also I measure frequency value with scope.
The frequency value is equal to each other. But when I convert…
Part Number: FDC2112 Hi,
We want to implement a collision warning function on a 6-axis collaborative robot, which can be automatic stop when approaching people.
We want to build some capacitive sensors on FPC and attach it to the surface of the robotic…
Part Number: FDC2112 Other Parts Discussed in Thread: FDC2114 For my application I used 3 FDC2112 to measure 5 sensors and one reference. The sensors are about 22pF PCB pads with no additional chip capacitors. The reference is just a PCB trace with no…
Part Number: FDC2112 Hello;
I use FDC2112 to measure multilayer capacitance.
Firstly, I connect 100pF capacitor differential mode like figure 55 on datasheet. It is ok. The measurement is true. Secondly I connect one more 100pF on paralell.
…
Part Number: FDC2112 I have a question about the input circuit of FDC2112 for use in a differential type circuit like the one below (the datasheet talks about using a 18uH inductor, and 33pF):
However, when looking at the layout, the 18uH inductor…
Part Number: FDC2112 Other Parts Discussed in Thread: FDC2114 Hi,
we are trying to interface TI’s FDC2112 with one of our products.
We tried configuring the IC as per the datasheet and were unable to see any result. We are able to read the Device…
