9. Effect on Absolute Accuracy: Attaching an external capacitor creates a coupling with ground,
Sensor
input
so if there is noise on the ground line, it may degrade absolute accuracy. The capacitor must be
connected to an electrically stable ground, such as AV
If a filter circuit is used, be careful of interference with digital signals on the same board, and
make sure the circuit does not act as an antenna.
