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 Other Parts Discussed in Thread: FDC2114 Hi! My application for the FDC2114 involves capacitance sensing of two pads that are spaced <5um apart. The datasheet says:
The single-ended configuration allows higher sensing range than…
Part Number: FDC2112 Hi,
In datasheet of FDC2112, on page 14, table 1 says that the valid fINx range is < Fref / 4. (As I understand it, fIN is the frequency of LC tank, divided by CHx_FIN_SEL)
But section 10.2.3.2 on page 42 says: The design constraint…
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, we are…
Part Number: FDC2112 Other Parts Discussed in Thread: LDC2114 Hi Team,
Would you advise TI has capacity sensor which can support from Vcc=2.0V?
I could not find it.
Thanks
Best regards,
Shidara
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: 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 = 0…
Part Number: FDC2112 Other Parts Discussed in Thread: FDC2114 Hi Sir,.
From the datasheet, the shutdown mode should be 200nA.
In our test on EVM and our PCBA, the FDC power is 1.9mA even we pull the SD pin to high (3.3V).
It seems that the SD pin could…
Part Number: FDC2112 Hi Ti
Assuming a system noise floor of < 10fF (Ti spec for FDC2x1x is 0.3 fF):
1) What is the LSB resolution (in fF) for 4 pF sensor capacitance using a sampling rate of 100 sps ?
2) What is the LSB resolution (in fF) for 4 pF…
Hi Dharmesh,
The FDC2114 is lower resolution, with only 12 bits. Investigate using the GAIN setting for the FDC2114 for greater sensitivity. You can refer to section 3.3 of the LDC131x application note for details ( www.ti.com/.../snoa945.pdf) , as the…
