  • The LC717A10PJ is a high-performance and low-cost capacitance-digital-converter LSI for electrostatic capacitive touch sensor, especially focused on usability. It has 16 channels capacitance-sensor input. This makes it ideal for use in the products that need many switches. Since the calibration function and the judgment of ON/OFF are automatically performed in LSI internal, it can make development time more short. A detection result (ON/OFF) for each input can be read out by the serial interface (I2C compatible bus or SPI). Also, measurement value of each input can be read out as 8-bit digital data. Moreover, gain and other parameters can be adjusted using serial interface.
  • 特性
  • Detection system: Differential capacitance detection (Mutual capacitance type) - High sensitivity performance - even wearing multiple layers of gloves, air gap, or thick materials
  • Input capacitance resolution: Can detect capacitance changes in the femto Farad order - Design friendly - can be connected directly to a familiar MCU and execute stand alone operation
  • Measurement interval (16 differential inputs):
    30ms (Typ) (at initial configuration
    6ms (Typ) (at minimum interval configuration) - Automated built-in noise and environmental change compensation function technology
  • External components for measurement: Not required
  • Interface: I2C compatible bus or SPI selectable.
  • Current consumption: 570 µA (Typ) (VDD = 2.8 V), 1.3 mA (Typ) (VDD = 5.5 V)
  • Supply voltage: 2.6 V to 5.5 V
  • Detection operations: Switch
