Onsemi LC717A00AR | Demoboard TS-GEVB
Capacitance-Digital-Converter for Electrostatic Capacitive Touch Sensors
Overview
| Topology | Other Topology |
Description
The LC717A00AR is a high-performance, low-cost capacitance-digital-converter LSI for electrostatic capacitive touch sensor, especially focused on usability. It has 8 channels capacitance-sensor input. The built-in logic circuit can detect the state (ON/OFF) of each input and output the result. This makes it ideal for various switch applications. The calibration function is automatically performed by the built-in logic circuit during power activation or whenever there are environmental changes. In addition, since initial settings of parameters, such as gain, are configured, LC717A00AR can operate as stand-alone when the recommended switch pattern is applied. Also, since LC717A00AR has a serial interface compatible with I2C and SPI bus, parameters can be adjusted using external devices whenever necessary. Moreover, outputs of the 8-input capacitance data can be detected and measured as 8-bit data.
Features
Detection system: Differential capacitance detection (Mutual capacitance type)
- High sensitivity performance - even wearing multiple layers of gloves, air gap, or thick materials
Input capacitance resolution: Can detect capacitance changes in the femto Farad order
- Design friendly - can be connected directly to a familiar MCU and execute stand alone operation
Measurement interval (8 differential inputs):18ms (Typ) (at initial configuration),3ms (Typ) (at minimum interval configuration)
- Automated built-in noise and environmental change compensation function technology
External components for measurement: Not required
Current consumption: 320 µA (Typ) (VDD = 2.8 V), 740 µA (Typ) (VDD = 5.5 V)
Supply voltage: 2.6 V to 5.5 V
Detection operations: Switch
Interface: I2C compatible bus or SPI selectable.
Typical applications
- Black goods / PC peripherals / Office Automation
- White goods
