DESCRIPTION  
The DS18B20 digital thermometer provides 9-bit  
to 12-bit Celsius temperature measurements and  
has an alarm function with nonvolatile user-  
programmable upper and lower trigger points.  
The DS18B20 communicates over a 1-Wire bus  
that by definition requires only one data line (and  
ground) for communication with a central  
microprocessor. It has an operating temperature  
range of -55°C to +125°C and is accurate to  
±0.5°C over the range of -10°C to +85°C. In  
addition, the DS18B20 can derive power directly  
from the data line (“parasite power”), eliminating  
the need for an external power supply.  
.
Available in 8-Pin SO (150 mils), 8-Pin µSOP,  
and 3-Pin TO-92 Packages  
.
.
Software Compatible with the DS1822  
Applications Include Thermostatic Controls,  
Industrial Systems, Consumer Products,  
Thermometers, or Any Thermally Sensitive  
System  
PIN CONFIGURATIONS  
Each DS18B20 has a unique 64-bit serial code,  
which allows multiple DS18B20s to function on  
the same 1-Wire bus. Thus, it is simple to use one  
microprocessor to control many DS18B20s  
distributed over a large area. Applications that  
can benefit from this feature include HVAC  
environmental controls, temperature monitoring  
systems inside buildings, equipment, or  
machinery, and process monitoring and control  
systems.
