TSM12S (12-CH Auto Sensitivity Calibration Capacitive Touch Sensor)
General
The TSM12S is 12-Channel capacitive sensor with auto sensitivity calibration. And the supply voltage range is from 1.8 to 5.0V.
The TSM12S has the SLEEP mode to save the consumption. And the current consumption is 8 u A.
The TSM12S offers fast touch detection with fast response operation.
The result of touch sensing can be checked by the I2C serial interface. And touch intensity can be detectable within 3 steps (Low, Middle and High).
