Other Parts Discussed in Thread: LDC2114, FDC2214
For a project I want to use multiple FDC1004 devices because I need more the 4 channels. Are the devices influencing each other measurements?

Hi Yibo,
Can you give more detail on"depend on the sensor setup"? I have to measure capacitance change on 16 area's at the same time. These 16 area's are all located in an square of 4cm by 4cm. Will one,area sensed by chip A be influenced by chip B which is sensing an other area. I will implement multiple I²C masters in an FPGA so I can address all the devices in parallel.

In my design I will have a 5cm connection to the sensing area. The connection trace will be very thin and will introduce a serie resistance of +/- 500 Ohm. What would be the effect on the capacitive measurement?
