0.25°C Accurate, 16-Bit Digital  
I2C Temperature Sensor  
Preliminary Technical Data  
ADT7420  
FEATURES  
GENERAL DESCRIPTION  
Temperature accuracy: 0.25°C from −20°C to +105°C  
13- or 16-bit user selectable temperature-to-digital converter  
Low drift silicon temperature sensor  
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 ADT7420 is a high accuracy digital temperature sensor  
offering breakthrough performance over a wide industrial  
range, housed in an LFCSP package. It contains a band gap  
temperature reference and a 13-bit ADC to monitor and digitize  
the temperature 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  
to 1 (Register Address 0x03).  
Operating temperature: −40°C to +150°C  
Operating voltage: 2.7 V to 5.5 V  
The ADT7420 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 ADT7420 has a shutdown mode that powers  
down the device and offers a shutdown current of typically 2 μA.  
The ADT7420 is rated for operation over the −40°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  
16-lead RoHS-compliant LFCSP package  
APPLICATIONS  
RTD and thermistor replacement  
Medical equipment  
Cold junction compensation  
Industrial control and test  
Food transportation and storage  
Environmental monitoring and HVAC  
Pin A0 and Pin A1 are available for address selection, giving the  
ADT7420 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.
