Part Number: FDC2112-Q1 Other Parts Discussed in Thread: FDC2112
Hi Team,
Good day, we received query from customer regarding incorrect capacitance readings. The customer is designing a dielectric meter using FDC2112. According to the customer, the…
Part Number: FDC2112 Other Parts Discussed in Thread: FDC2114EVM Hello,
may I use a gain amplifier to increase sensor excitation voltage.
if yes, when i increase the voltage, is measurement more precisely.
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…
Part Number: FDC2112 Hello, We have a customer that brought this to our attention:
The screenshot is from the datasheet, page 39. May we please request for confirmation if this is a typo? Should it be "when using a 'differential sensor' configuration…
Part Number: CC2541 Other Parts Discussed in Thread: FDC2112 Hi YiKai Chen Bluetooth forum ,
Do we have any example code or library available for FDC2112. I want to code for FDC2112 with CC2541 but I have no clue, how to do.
Regards,
Yatin …
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 Other Parts Discussed in Thread: SN74LVC1G66 , LDC2114 , FDC2114 , LDC1314 , FDC2214 Hi All
I would like to know if I could adapt the fdc2112 into our sensing design to replace current capacitance sensing so that we get further…
Hi Steve,
The FDC2112 measures the frequency change of the sensor LC tank to determine the change in capacitance. It converts the sensor frequency into a digital value representing the ratio of the sensor frequency to the reference frequency (clock…
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…
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
