LC717A10AJ

Ordering number : ENA2162 CMOS LSI LC717A10AJ Overview Capacitance-Digital-Converter LSI for Electrostatic Capacitive Touch Sensors 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. 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): 30ms (Typ) (at initial configuration), 6ms (Typ) (at minimum interval configuration) External components for measurement: Not required Interface: I2C * compatible bus or SPI selectable. Current consumption: 570μA (Typ) (VDD = 2.8V), 1.3mA (Typ) (VDD = 5.5V) Supply voltage: 2.6V to 5.5V Detection operations: Switch Packages: SSOP30 * I2C Bus is a trademark of Philips Corporation.
