ON Semiconductor – LC717A30UJ: Highly Integrated Capacitive-Digital Converter Delivers Superior Gesture Sensing


The LC717A30UJ is a high performance, low cost, and highly usable capacitance converter for electrostatic capacitive touch and proximity sensors. 8 capacitancesensing input channels ideal for use in any end products that needs an array of switches. The detection result (ON/OFF) for each sensor is read out by the serial interface (I2C or SPI). As the device’s sensitivity has a range of 150 millimeters (mm) – beyond the scope of any competing device on the market – its higher sensitivity enables gesture motions as well as offering conventional touch functionality, thereby enhancing users’ control options to address a wide range of application scenarios.
