ON LC717A00ARZ-NH

按钮无I²C，SPI2.6V ~ 5.5V-40°C ~ 105°C

Overview

The LC717A00AR-NH 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-NH can operate as stand-alone when the recommended switch pattern is applied. Also, since LC717A00AR-NH 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.
