Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
SHLD1 1 A Capacitive Input Active AC Shielding.
CIN1 2 A Capacitive Input. The measured capacitance is connected between the CIN1 pin and GND. If not used, this pin should be left as an open circuit.
CIN2 3 A Capacitive Input. The measured capacitance is connected between the CIN2 pin and GND. If not used, this pin should be left as an open circuit.
CIN3 4 A Capacitive Input. The measured capacitance is connected between the CIN3 pin and GND. If not used, this pin should be left as an open circuit.
CIN4 5 A Capacitive Input. The measured capacitance is connected between the CIN4 pin and GND. If not used, this pin should be left as an open circuit.
SHLD2 6 A Capacitive Input Active AC Shielding.
GND 7 G Ground
VDD 8 P Power Supply Voltage. This pin should be decoupled to GND, using a low impedance capacitor, for example in combination with a 1-μF tantalum and a 0.1-μF multilayer ceramic.
SCL 9 I Serial Interface Clock Input. Connects to the master clock line. Requires pull-up resistor if not already provided elsewhere in the system.
SDA 10 I/O Serial Interface Bidirectional Data. Connects to the master data line. Requires a pull-up resistor if not provided elsewhere in the system.
(1) P=Power, G=Ground, I=Input, O=Output, A=Analog, I/O=Bi-Directional Input/Output
