TINY SOT563 PACKAGE  
The TMP112 is a two-wire, serial output temperature  
sensor available in a tiny SOT563 package. Requiring  
no external components, the TMP112 is capable of  
reading temperatures to a resolution of 0.0625°C.  
The TMP112 slope-specification allows users to  
calibrate for higher accuracy.  
ACCURACY:  
0.5°C (max) from 0°C to +65°C  
1.0°C (max) from –40°C to +125°C  
LOW QUIESCENT CURRENT:  
10µA Active (max), 1µA Shutdown (max)  
The TMP112 features both SMBus and two-wire  
interface compatibility, and allows up to four devices  
on one bus. It also features an SMBus alert function.  
SUPPLY RANGE: 1.4V to 3.6V  
RESOLUTION: 12 Bits  
DIGITAL OUTPUT: Two-Wire Serial Interface  
The TMP112 is ideal for extended temperature  
measurement  
consumer,  
instrumentation applications. It is specified for  
operation over a temperature range of –40°C to  
+125°C.
