LM95172EWG is AEC-Q100 Grade 0 Qualified  
and is Manufactured on an Automotive Grade  
Flow.  
DESCRIPTION  
•
13-Bit (0.0625°C LSB) to 16-Bit (0.0078125°C  
LSB) Temperature Resolution  
The LM95172EWG is an integrated digital-output  
temperature sensor with a Serial Peripheral Interface  
(SPI) and MICROWIRE™-compatible interface in a  
10-pin Cerpack high temperature ceramic package. It  
features a very linear Sigma-Delta Analog-to-Digital  
Converter (ADC), high accuracy, fast conversion  
rates, and extremely low output noise. With an  
operating temperature as low as -40°C and optimized  
accuracy from 120°C to 200°C, it is ideal for high-  
temperature applications.

Automotive High Temperature Applications  
Industrial Power Controllers  
The LM95172EWG can be programmed to operate  
from 13 bits (0.0625°C per LSB) to 16 bits  
(0.0078125°C  
per  
LSB)  
resolution.  
The  
Industrial Motors, Gear Boxes  
Geothermal Instrumentation  
LM95172EWG powers up in 35 ms, the fastest  
conversion time, with temperature output set at 13-bit  
resolution. The resolution may then be changed to  
14-, 15- or 16-bits. When in the 13-, 14- or 15-bit  
resolution mode, the least significant bit in the 16-bit  
temperature register toggles after the completion of  
each conversion. This bit may be monitored to verify  
that the conversion is complete.
