FEATURES  
GENERAL DESCRIPTION  
13- or 16-bit user selectable temperature-to-digital converter  
Temperature accuracy: 0.5°C from −40°C to +105°C  
No temperature calibration/correction required by user  
Power saving 1 sample per second (SPS) mode  
Fast first conversion on power-up of 6 ms  
I2C-compatible interface  
The ADT7410 is a high accuracy digital temperature sensor  
in a narrow SOIC package. It contains a band gap temperature  
reference and a 13 bit ADC to monitor and digitize the temper-  
ature to a 0.0625°C resolution. The ADC resolution, by default,  
is set to 13 bits (0.0625°C). This can be changed to 16 bits  
(0.0078°C) by setting Bit 7 in the configuration register  
(Register Address 0x03).  
Operating temperature: −55°C to +150°C  
Operating voltage: 2.7 V to 5.5 V  
The ADT7410 is guaranteed to operate over supply voltages from  
2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typi-  
cally 210 μA. The ADT7410 has a shutdown mode that powers  
down the device and offers a shutdown current of typically 2 μA.  
The ADT7410 is rated for operation over the −55°C to +150°C  
temperature range.  
Critical overtemperature indicator  
Programmable overtemperature/undertemperature interrupt  
Low power consumption: 700 μW typical at 3.3 V  
Shutdown mode for lower power: 7 μW typical at 3.3 V  
8-lead narrow SOIC RoHS-compliant package  
APPLICATIONS  
Medical equipment  
Pin A0 and Pin A1 are available for address selection, giving the  
ADT7410 four possible I2C® addresses. The CT pin is an open-  
drain output that becomes active when the temperature exceeds  
a programmable critical temperature limit. The default critical  
temperature limit is 147°C. The INT pin is also an open-drain  
output that becomes active when the temperature exceeds a  
programmable limit. The INT and CT pins can operate in either  
comparator or interrupt mode.
