DESCRIPTION

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. The DS18B20 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 ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.

FEATURES

● Unique 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; 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 750ms (Max)

● User-Definable Nonvolatile (NV) Alarm Settings

● Alarm Search Command Identifies and Addresses Devices Whose Temperature is Outside Programmed Limits (Temperature Alarm Condition)

● Available in 8-Pin SO (150 mils), 8-Pin μSOP,and 3-Pin TO-92 Packages

● Software Compatible with the DS1822

● Applications Include Thermostatic Controls, Industrial Systems, Consumer Products, Thermometers, or Any Thermally Sensitive System
