Description
Ground Pin.
Power Supply Voltage. This pin should be decoupled to GND using a low impedance capacitor, for example,
0.1 μF X7R multilayer ceramic.
CDC Capacitive Input Channel 2. The measured capacitance (sensor) is connected between the EXC2 pin and
the CIN2 pin. If not used, this pin can be left open circuit or connected to GND.
CDC Capacitive Input Channel 1. The measured capacitance (sensor) is connected between the EXC1 pin and
the CIN1 pin. If not used, this pin can be left open circuit or connected to GND.
CDC Excitation Output Channel 2. The measured capacitance is connected between the EXC2 pin and the
CIN2 pin. If not used, this pin should be left as an open circuit.
CDC Excitation Output Channel 1. The measured capacitance is connected between the EXC1 pin and the
CIN1 pin. If not used, this pin should be left as an open circuit.
Logic Output Channel 1. A high level on this output indicates proximity detected on CIN1.
Logic Output Channel 2. A high level on this output indicates proximity detected on CIN2.
Serial Interface Clock Input. Connects to the master clock line. Requires a pull-up resistor if not provided
elsewhere in the system.
Serial Interface Bidirectional Data. Connects to the master data line. Requires a pull-up resistor if not provided
elsewhere in the system.
