DS18B20 Programmable Resolution 1-Wire® Digital Thermometer
FEATURESUnique 1-wire interface requires only one port pin for communication
Each device has a unique 64-bit serial code stored in an on-board ROM
Multi-drop capability simplifies distributed temperature sensing applications
Requires no external components
Can be powered from data line. Power supply range is 3.0V to 5.5V
Measures temperatures from –55°C to +125°C (–67°F to +257°F)
±0.5°C accuracy from –10°C to +85°C
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 alarm settings
Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
Software compatible with the DS1822
Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system.
