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 the differential configuration for a given total sensor plate area. In applications in which high sensitivity at close proximity is desired, the differential configuration performs better than the single-ended configuration.
Could you elaborate on why the differential configuration performs better? Thank you!
