DS18B20  
Programmable Resolution  
1-Wire Digital Thermometer  
General Description  
Benefits and Features  
● Unique 1-Wire Interface Requires Only One Port  
®
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 micro-  
processor. In addition, the DS18B20 can derive power  
directly from the data line (“parasite power”), eliminating  
the need for an external power supply.  
Pin for Communication  
● Reduce Component Count with Integrated  
Temperature Sensor and EEPROM  
• Measures Temperatures from -55°C to +125°C  
(-67°F to +257°F)  
• ±0.5°C Accuracy from -10°C to +85°C  
• Programmable Resolution from 9 Bits to 12 Bits  
• No External Components Required  
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.  
● Parasitic Power Mode Requires Only 2 Pins for  
Operation (DQ and GND)  
● Simplifies Distributed Temperature-Sensing  
Applications with Multidrop Capability  
• Each Device Has a Unique 64-Bit Serial Code  
Stored in On-Board ROM  
● Flexible User-Definable Nonvolatile (NV) Alarm Settings  
with Alarm Search Command Identifies Devices with  
Temperatures Outside Programmed Limits  
Applications  
● Thermostatic Controls  
● Available in 8-Pin SO (150 mils), 8-Pin µSOP, and  
● Industrial Systems  
3-Pin TO-92 Packages  
● Consumer Products  
● Thermometers  
● Thermally Sensitive Systems
