1

SCLK

Serial Clock Input. The serial clock is used to clock in and clock out data to and from any register of the ADT7310.

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 part’s control registers 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 selected when this input is low. The device is disabled when this pin is high.

5

INT

Overtemperature and Undertemperature Indicator. 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.

6

CT

Critical Overtemperature Indicator. Logic output. Power-up default polarity is active low. Open-drain

configuration. A pull-up resistor is required, typically 10 kΩ.

7

GND

Analog and Digital Ground.

8

VDD

Positive Supply Voltage (2.7 V to 5.5 V). The supply should be decoupled with a 0.1 μF ceramic capacitor to

ground.
