LC717A10AJ
Capacitance‐Digital‐Converter LSI for Electrostatic Capacitive Touch Sensors
Overview The LC717A10AJ 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.
