AD7142/AD7142-1 is a programmable capacitance-to-digital converter with environmental compensation, which can be used in personal music and multimedia systems.
The AD7142 and AD7142-1 are integrated capacitance-to-digital converters (CDCs) designed with on-chip environmental calibration for systems requiring novel user input methods. These devices interface to external capacitance sensors, such as capacitive buttons, scroll bars, or joypads, by sensing changes in sensor capacitance and registering activation events.
