LC717A30UR中文资料Capacitance-Digital-Converter for Electrostatic Capacitive Touch Sensors数据手册ONSEMI规格书

描述 Description

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).

特性 Features

• 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.
• 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

应用 Application

• Automotive
• Consumer
• Industrial
• Computing
• Lighting
• Smart key, Control switches, Car audio and Proximity
• Home Appliance, White goods and Induction Cooking
• Security lock
• PC Peripherals, Audio Visual equipment
• Remote control switches
