LC717A00AJ Capacitance‐Digital‐Converter LSI for Electrostatic Capacitive Touch Sensors Overview 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.
