I'm confused by accuracy and resolution. I'm designing capacitive sensor that has a baseline capacitance of ~ 1 pF. If I'm understanding the datasheet correctly, the capacitance-to-digital converter will read and output the capacitance somewhere between 0.996-1.004 pF (accuracy)? Assuming the output is 0.998 pF (within the range above) will the chip then be able to read out the difference between 0.997994 pF and 0.998004 pF?
Also, the resolution is at 0.4 aF, does any other aspect of the sensor have to be limited (i.e. sampling rate)?
