引脚定义与内部结构

数据来源：原厂规格书引脚图

The TS08N is 8-Channel capacitive sensor with auto sensitivity calibration.
It detects capacitance variation of CS port. and outputs result to the out port with open drain
NMOS structure.
The R_BIAS port decides bias current by external resister value. The bias current influences system oscillator frequency and sensing frequency also current consumption.
The TS08N can be operated at low voltage supply.
The supply voltage range is from 1.8V to 5.5V.
The TS08N is reset by external device and external signal.
Block Diagram
 8-Channel capacitive sensor with auto sensitivity calibration
 Selectable output operation (single or multi output mode)
 Low current consumption
 Uniformly adjustable 2 step sensitivity
 Sync function for parallel operation
 Adjustable internal frequency with external resister
 Selectable sense line impedance out of scanning
 Open-drain digital output
