SNOSCY5C August 2014 – October 2024 FDC1004
PRODUCTION DATA
Avoid long traces to connect the sensor to the FDC1004. Short traces reduce parasitic capacitances between shield versus input channel and parasitic resistance between input channel versus GND and shield versus GND.
The sensor in many cases is simply a metal surface on a PCB, therefore the sensor must be protected with solder resist to avoid short circuits and limit any corrosion. Any change in the sensor can result in a change in system performance.
