smart board sb680 manual
smart board sb680 manual.This operation causes the sample/hold capacitor CHOLD to be in parallel with the sensor capacitor, forming a voltage divider between the two. Therefore, the voltage across the sensor capacitor is equal to the voltage across the sample/hold capacitor. The ADC is sampled and its reading represents the ratio of the two capacitors. When the finger touches the sensor, the capacitance of the sensor increases. As a result, the voltage on the sensor will decrease and the ADC reading will increase.
