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 non-volatile temperature
alarm settings
• Alarm search command identifies and
addresses devices whose temperature is
outside of programmed limits (temperature
alarm condition)
• 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
