FDC2112: which chip to perform detection using a big size coplanar sensor

Part Number: FDC2112
Other Parts Discussed in Thread: FDC1004, , FDC2212


I'm actually needing your advise for product/part number(s).
We're setting up an application with big size conductive sensor to measure small/low profile objects with a coplanar configuration. We think we need a capacitive to voltage detection chip.

We did try the FDC1004 before, but it has a small offset limiting the possibility of large conductors as sensor.

I'm checking the FDC2112 as an option, but perhaps you recommand other options as well?

As for the FDC 1004 resp. FDC2112, what kind of excitation signal is outputted? Is it a sine? Square? Please define.

As for the FDC2112, it possible to change the input frequency. Should this be a sine or square wave signal?
