NOTES
1. NC = NO CONNECT. DO NOT CONNECT TO THIS PIN.
THE NC PIN IS NOT BONDED TO THE DIE INTERNALLY.
2. TO ENSURE CORRECT OPERATION, THE EXPOSED PAD
SHOULD EITHER BE LEFT FLOATING OR CONNECTED
TO GROUND.

Pin No. Mnemonic Description
1
SCLK
Serial Clock Input. The serial clock is used to clock data into and out of any register of the ADT7320.
2
DOUT
Serial Data Output. Data is clocked out on the SCLK falling edge and is valid on the SCLK rising edge.
3
DIN
Serial Data Input. Serial data to be loaded to the control registers of the part is provided on this input. Data is
clocked into the registers on the rising edge of SCLK.
4
CS
Chip Select Input. The device is enabled when this input is low. The device is disabled when this pin is high.
5
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
6
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
7
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
8
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
9
INT
Overtemperature and Undertemperature Interrupt. Logic output. Power-up default setting is as an active low
comparator interrupt. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
10
CT
Critical Overtemperature Interrupt. Logic output. Power-up default polarity is active low. Open-drain
configuration. A pull-up resistor is required, typically 10 kΩ.
11
GND
Analog and Digital Ground.
12
VDD
13
NC
Positive Supply Voltage (2.7 V to 5.5 V). Decouple the supply with a 0.1 μF ceramic capacitor to GND.
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
14
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
15
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
16
NC
No Connect. Do not connect to this pin. The NC pin is not bonded to the die internally.
17
EPAD
Exposed Pad. To ensure correct operation, the exposed pad should either be left floating or connected to ground.
