LC717A10AR Datasheet | SANYO

Ordering number : ENA2161 CMOS LSI Overview Capacitance-Digital-Converter LSI for Electrostatic Capacitive Touch Sensors 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 (I2C 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): 30ms (Typ) (at initial configuration), 6ms (Typ) (at minimum interval configuration) - External ponents for measurement: Not required - Interface: I2C - patible bus or SPI selectable. - Current consumption: 570μA (Typ) (VDD = 2.8V), 1.3m A (Typ) (VDD = 5.5V) - Supply voltage: 2.6V to 5.5V - Detection operations: Switch - Packages: VCT28 - I2C Bus is a trademark of Philips Corporation.
