LC71F7001PVBS0数据手册集成电路（IC）的传感器电容式触控规格书PDF

描述 Description

The LC71F7001PVB is capacitance digital converter LSI designed for electrostatic capacitance touch sensors. A total of 14 capacitance sensors (7 pairs with 14 sensors in the differential input mode) can be connected to the input pin and, depending on how the sensors are combined, 14 or more switch functions can be provided. The LC71F7001PVB is also provided with up to 14 general-purpose output ports (GPO) that can be used as LED drive ports. The detected capacitance values are output as 16-bit digital data through the I2C serial interface. The detection sensitivity and capacitance offset value can be adjusted and set (calibrated) from an external device through the I2C serial interface.
