1

SCL

I2C Serial Clock Input. The serial clock is used to clock in and clock out data to and from any register of the ADT7410.

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

2

SDA

I2C Serial Data Input/Output. Serial data to and from the part is provided on this pin. Open-drain configuration. A

pull-up resistor is required, typically 10 kΩ.

3

A0

4

A1

I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or VDD to set an I2C address.

I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or VDD to set an I2C address.

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.
