The LC717A30UJ 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 LC717A30J 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).
Detection system: Differential capacitive detection using mutual capacitance - Superior sensitivity performance - even not only wearing multiple layers of gloves, air gap, or thick materials but also gesture.
Sensor input pads: Operates with small to large capacitance sensor input pads - Reducing cost because of being unnecessary to supplement sensitivity.
Input capacitance resolution: Capacitance detection down to femto-Farad level - Achieving layout freely because of receiving hardly from parasitic capacitance.
Measurement time 16 ms for 8 sensors - High adaptability by internal both noise reduction and correspondence system for environment changing.
Minimal external components - Advantage tolerance for malfunction prevention of water.
