Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
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 to capacitor…
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 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.
So my reading…
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 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 you
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…
Part Number: FDC2112 Hi. I am completely new to this segment of electronics and I got little bit confused.
In my device the surface area of sensing should be around 30 x 30 cm.
I was reading http://www.ti.com/lit/ds/symlink/fdc2212-q1.pdf and http://www…
Part Number: FDC2112 Other Parts Discussed in Thread: LDC1612 Hello Team,
Is it possible for FDC to achieve following measurement?
*Wafer flatness inspection
Distance from sensor to wafer 14mm or 25mm
Resolution 0.1mm
Sampling rate 150sps
Best regards…
Part Number: FDC2112-Q1 Other Parts Discussed in Thread: FDC2112 Hello,
we are using FDC2112 on our module along with GNSS receiver (in combination with chip antenna). The chip antenna is 15 mm away from the FDC LC tank.
During GNSS testing on our module…
