AD7152 Pin Configuration NC = NO CONNECT GND 1 VDD 2 CIN1(–) 3 CIN1(+) 4 NC 5 SDA 10 SCL 9 NC 8 NC 7 EXC1 6 AD7153 TOP VIEW (Not to Scale) Figure 5. AD7153 Pin Configuration Table 4. Pin Function Descriptions Pin No. Mnemonic Description 1 GND Ground Pin. 2 VDD Power Supply Voltage. This pin should be decoupled to GND, using a low impedance capacitor, for example, in combination with a 10 μF tantalum and a 0.1 μF multilayer ceramic capacitor. 3 CIN1(–) CDC Negative Capacitive Input of Channel 1. If not used, this pin can be left as an open circuit or connected to GND. This pin is internally disconnected in single-ended CDC configuration. 4 CIN1(+) CDC Positive Capacitive Input of Channel 1. If not used, this pin can be left as an open circuit or connected to GND. 5 EXC2/NC AD7152: CDC Excitation Output for Channel 2. The measured capacitance is connected between one of the EXC pins and one of the CIN pins. If not used, these pins should be left as an open circuit. AD7153: No Connect. This pin must be left as an open circuit. 6 EXC1 CDC Excitation Output for Channel 1. The measured capacitance is connected between one of the EXC pins and one of the CIN pins. If not used, these pins should be left as an open circuit. 7 CIN2(+)/NC AD7152: CDC Positive Capacitive Input of Channel 2. If not used, this pin can be left as an open circuit or connected to GND. AD7153: No Connect. This pin must be left as an open circuit. 8 CIN2(–)/NC AD7152: CDC Negative Capacitive Input of Channel 2. If not used, this pin can be left as an open circuit or connected to GND. This pin is internally disconnected in single-ended CDC configuration. AD7153: No Connect. This pin must be left as an open circuit. 9 SCL Serial Interface Clock Input. Connects to the master clock line. Requires a pull-up resistor if one is not already provided in the system. 10 SDA Serial Interface Bidirectional Data. Connects to the master data line. Requires a pull-up resistor if one is not provided elsewhere in the system. |
