LC717A30UJ: Capacitance-Digital-Converter for Electrostatic Capacitive Touch Sensors

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).

Features
  • Detection system: Differential capacitive detection using mutual capacitance
  • Sensor input pads: Operates with small to large capacitance sensor input pads
  • Input capacitance resolution: Capacitance detection down to femto-Farad level
  • Measurement time 16 ms for 8 sensors
  • Minimal external components
  • Selectable interface : I2C or SPI
  • Current consumption : 0.8 mA (VDD = 5.5 V)
  • Supply voltage : 2.6 to 5.5 V
  • AEC-Q100 qualified and PPAP capable
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.
