NOTES
1. NC = NO CONNECT.
2. THE EXPOSED PAD IS CONNECTED INTERNALLY.
FOR INCREASED RELIABILITY OF THE SOLDER JOINTS
AND MAXIMUM THERMAL CAPABILITY IT IS RECOMMENDED
THAT THE PAD BE SOLDERED TO THE GROUND PLANE.

Description
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 ADT7420.
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
I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or V
DD to set an I
2C address.
4
A1
I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or V
DD to set an I
2C address.
5
NC
No Connect.
6

No Connect.
8
NC
No Connect.
9
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.
10
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.
11
GND
Analog and Digital Ground.
12
V
DD
Positive Supply Voltage (2.7 V to 5.5 V). The supply should be decoupled with a 0.1 µF ceramic capacitor to ground.
13
NC
No Connect.
14

No Connect.
15
NC
No Connect.
16
NC
No Connect.
