Base chip for Arduino touch sensors. Can be used as a physical contact detector, low energy consumption.
Technical data:
Operating voltage 2.0V~5.5V
Low power mode
Operating current @VDD=3V no load at low power mode typical 2.0uA , maximum 4.0uAResponse time max 220ms at low power mode @VDD=3V
Sensitivity can be adjusted by providing outer capacitance 1~50pF
Provides direct output selection by pin option(TOG pin)
Q pin is CMOS output can be selected active high or active low by pin option (AHLB pin)
After power-on approx. 0.5sec is required for stabilizing
Auto calibration.
Recalibration time is 1sec within 8 sec after power-on. When touch has been detected within 8 sec or it has not been detected for more than 8 sec after power-on, the re-calibration time changes to 4 sec
