 Capacitance-Digital-Converter for Electrostatic Capacitive Touch Sensors

制造商:ON

中文数据手册

产品信息

The LC717A00AJ is a high-performance, low-cost capacitance-digital-converter LSI for electrostatic capacitive touch sensor, especially focused on usability. It has 8 channels capacitance-sensor input. The built-in logic circuit can detect the state (ON/OFF) of each input and output the result. This makes it ideal for various switch applications. The calibration function is automatically performed by the built-in logic circuit during power activation or whenever there are environmental changes. In addition, since initial settings of parameters, such as gain, are configured, LC717A00AJ can operate as stand-alone when the recommended switch pattern is applied. Also, since LC717A00AJ has a serial interface compatible with I
C and SPI bus, parameters can be adjusted using external devices whenever necessary. Moreover, outputs of the 8-input capacitance data can be detected and measured as 8-bit data.
  • Detection system: Differential capacitance detection (Mutual capacitance type)
  • Input capacitance resolution: Can detect capacitance changes in the femto Farad order
  • Measurement interval (8 differential inputs):
  • 18ms (Typ) (at initial configuration),
  • 3ms (Typ) (at minimum interval configuration)
  • External components for measurement: Not required
  • Current consumption: 320 µA (Typ) (V
  • = 2.8 V), 740 µA (Typ) (V
  • = 5.5 V)
  • Supply voltage: 2.6 V to 5.5 V
  • Detection operations: Switch
  • Interface: I
  • C compatible bus or SPI selectable.
