Part Number: FDC1004-Q1 Other Parts Discussed in Thread: FDC1004 , FDC2214 Hi,
I am going to use FDC1004 for more than 100pF capacity measurment. Is there any circuit or solution to extend capacitive input range like AD7745 IC from Analog Device?
Best regards…
Part Number: FDC1004-Q1 Hi all,
One of the FDC1004-Q1 chips I am using for prototyping liquid sensing is behaving "oddly".
Specifically, I can read/write to the FDC register (0x0C) but I can not read to any of the MEAS* registers {0x08, 0x09…
Part Number: FDC1004-Q1 Dear all,
We think to add varistor between sensor and CINx in order to protect IC from ESD.
Is this way correct? Can I add passive device between sensor and CINx?
Best regards,
Part Number: FDC1004-Q1 Dear all,
Can we set the assignment of shield 1/2?
* For example, assigning shield 1 to CH1/2/3 and shield 2 to CH4.
And can we set the use of shield?
* For example, assigning shield 1 to CH1, assigning sheld 2 to CH2, and CH3…
Part Number: FDC1004-Q1 Other Parts Discussed in Thread: FDC1004 Hello, I am learning about I2C "fdc1004q" communication in Arduino. This datasheet suggest Device Usage :

Zirui,
We are unaware of anyone using the FDC1004-Q1 for ambient lighting control. Most applications we know have been for liquid-level sensing, It may be that FDC1004-Q1 has been used in ambient lighting applications, but we are unaware of it.
If your…
Dear all,
I would like to check one thing.
I have understood that this device read capacitance value one after another by MUX.
In other words, this device read CIN1>CIN2>CIN3>CIN4>CIN1>・・・.
■Question
Are the pin ''not'' being read OPEN…

Hi Patrick, 1) The shielding capability is fairly effective in reducing the effects of parasitic capacitances. If the noise comes from environmental sources that affect the charge on the capacitors (like fluorescent lights), the shielding will not help…
Hello HS,
In the FDC1004-Q1 datasheet there is a reference to and block diagram for a rain-sensor application for automobile: www.ti.com/lit/ds/symlink/fdc1004-q1.pdf .
And there is another E2E post addressing this application: https://e2e.ti.com/support…
