TS08N (8-CH Auto Sensitivity Calibration Capacitive Touch Sensor) General
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.
