Semiconductor device for determining whether touch electrode is touched by human body, and touch sensor using the semiconductor device |
摘要 |
A touch sensor IC includes a switch for connecting, to an external terminal with its voltage to be sensed, a selected one of a plurality of external terminals to which a plurality of touch electrodes is connected. Only one set of two capacitors and a resistor element may therefore be provided for a plurality of touch electrodes. Thus, the number of required components is smaller as compared with a conventional sensor requiring two capacitors and a resistor element for each touch electrode. |
