DESCRIPTION  
The DS1822 digital thermometer provides 9- to 12-bit centigrade temperature measurements and has an  
alarm function with NV user-programmable upper and lower trigger points. The DS1822 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  
±2.0°C over the range of –10°C to +85°C. In addition, the DS1822 can derive power directly from the  
data line (“parasite power”), eliminating the need for an external power supply.  
Each DS1822 has a unique 64-bit serial code, which allows multiple DS1822s to function on the 1-Wire  
bus; thus, it is simple to use one microprocessor to control many DS1822s 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.
