ANMG04 (4-CH Auto Sensitivity Calibration Capacitive Touch Sensor)
4 Pin Description
VDD, GND
Supply voltage and ground pin.
R.N.D
Radio frequency Noise Detection pin. Normally, R.N.D pin does not connect to anywhere.
But, in radio frequency noise environment, this pin must form a pattern line on PCB.
CS1 ~ CS4
Capacitive sensor input pins.
LCAP
Internal LDO output port.
D1 ~ D4
Parallel output ports of CS1~CS4 respectively / LED PWM drive output ports. The structure of these parallel
output ports is open drain NMOS for active low output level operation.
SCL, SDA
SCL is I2C clock input pin and SDA is I2C data input-output pin. These ports have internal pull-up resistor.
In case of not use, this pin must be not connected to any circuitry.
