Programmable Resolution 1-Wire Digital Thermometer

DESCRIPTION The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20 over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central micro

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.

FEATURES  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  Multidrop Capability Simplifies Distributed Temperature-Sensing Applications  Requires No External Components Can Be Powered from Data Line;
