摘要： A single integrated circuit for operating both a capacitive proximity sensor device and a resistive pointing stick comprises sensor circuitry to drive a first varying voltage signal onto a transmitter electrode of the capacitive proximity sensor device. The sensor circuitry is also configured to drive a second varying voltage signal onto a voltage divider of the pointing stick and a third varying voltage signal onto the voltage divider of the pointing stick. The sensor circuitry is configured to receive a first resulting signal from a receiver electrode of the proximity sensor device and receive a second resulting signal from the pointing stick. The single integrated circuit includes determining circuitry configured to determine positional information for input received in a sensing region of the proximity sensor device based on the first resulting signal; and to determine force information received as input to the pointing stick based on the second resulting signal.
