[AK4161] AK4161 6-channel Capacitive Touch Sensor IC GENERAL DESCRIPTION The AK4161 is a low operating voltage and low power consumption 6-channel capacitive touch sensor. Maximum 6 input channels can be configured to LED drive or GPIO. 2 channels out of 6-channel can also be configured to interrupt output. The AK4161 has a channel independent automatic correct function of environmental drifts for each sense input. It reduces false detection by continuous calibration of the internal reference value in the situation when the input capacitance of the touch switch is changed by the external factors such as hydrothermal conditions. The automatic initial setting function sets the charge current and charge time according to the size and the shape of a touch switch.
