Product Details

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 judgement of ON/OFF are automatically performed in LSI internal, it can make development time more short.

Differential capacitance detection (Mutual capacitance type)
Can detect capacitance changes in the femto Farad order
High sensitivity performance - even wearing multiple layers of gloves, air gap, or thick materials
Design friendly - can be connected directly to a familiar MCU and execute stand alone operation
Automated built-in noise and environmental change compensation function technology
External components for measurement: Not required
Interface: I2C compatible bus or SPI selectable.
Detection operations: Switch
