The LC717A30UR is a high performance， low cost， and_highly usable capacitance converter for electrostatic capacitive touch and_proximity sensors.
8 capacitance-sensing input channels ideal for use in any end products that needs an array of switches. The LC717A30UR facilitates a short system development time through its automatic calibration function and_minimal external components. The detection result (ON/OFF) for each sensor is read out by the serial interface (I2C or SPI).

ON Semiconductor LC717A30UR Capacitance-Digital-Converter for Electrostatic Capacitive Touch Sensors
Benefits
?Superior sensitivity performance - even not only wearing multiple layers of gloves， air gap， or thick materials but also gesture.
?Reducing cost because of being unnecessary to supplement sensitivity.
?Achieving layout freely because of receiving hardly from parasitic capacitance.
?High adaptability by internal both noise reduction and_correspondence system for environment changing.
?Advantage tolerance for malfunction prevention of water.
