FEATURES
Unique 1-Wire interface requires only one
port pin for communication
Derives power from data line (“parasite
power”)—does not need a local power supply
Multi-drop capability simplifies distributed
temperature sensing applications
Requires no external components
±0.5°C accuracy from –10°C to +85°C
Measures temperatures from –55°C to
+100°C (–67°F to +212°F)
Thermometer resolution is user-selectable
from 9 to 12 bits
Converts temperature to 12-bit digital word in
750 ms (max.)
User–definable

Software compatible with the DS1822-PAR
Ideal for use in remote sensing applications
(e.g., temperature probes) that do not have a
local power source

DESCRIPTION
The DS18B20-PAR digital thermometer provides 9 to 12–bit centigrade temperature measurements and
has an alarm function with nonvolatile user-programmable upper and lower trigger points.
The
DS18B20-PAR does not need an external power supply because it derives power directly from the data
line (“parasite power”).
The DS18B20-PAR communicates over a 1-Wire bus, which 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 +100°C and is accurate to
±0.5°C over a range of –10°C to
+85°C.
Each DS18B20-PAR has a unique 64-bit identification code, which allows multiple DS18B20-PARs to
function on the same 1–wire bus; thus, it is simple to use one microprocessor to control many DS18B20-
PARs 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.
