Capacitance‐Digital‐Converter LSI for Electrostatic Capacitive Touch Sensors Overview The LC717A10AR 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 (I2Ct patible 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. Features - Detection System: Differential Capacitance Detection (Mutual Capacitance Type) - Input Capacitance Resolution: Can Detect Capacitance Changes in the Femto Farad Order - Measurement Interval (16 Differential Inputs): - 30 ms (Typ) (at Initial Configuration) - 6 ms (Typ) (at Minimum Interval Configuration) - External ponents for Measurement: Not Required - Current Consumption: - 570 m A (Typ) (VDD = 2.8 V) - 1.3 m A (Typ) (VDD = 5.5 V) - Supply Voltage: 2.6 V to 5.5 V - Detection Operations: Switch - Interface: I2C patible Bus or SPI Selectable .onsemi.
