What is the output of the MC33794 I will see or use?
The output of the MC33794 is the LEVEL or SIGNAL pin. The user sees the output of the internal low-pass RC filter with capacitance set by the capacitance to the LPF pin filtered. The processed signal is presented at the LEVEL pin. Alternatively, the user may decide to look at the gained, but detected and unfiltered, output signal at the SIGNAL pin. In either case, the detected voltage it that sensed at one of the eight electrodes, which are selected for processing by setting the sense electrodes BCD value at the A, B, C, or D inputs. At this point, the users application may digitize the value or use it in real time to compare to a threshold and control something if the value meets the threshold criteria.
