Product Summary

The DS18B20+ is designed as one kind of programmable resolution 1-Wire digital thermometer. This device can be used in thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system. And it has an 8-bit CRC stored in the most significant byte of the 64-bit ROM and also generates an 8-bit CRC value using the same polynomial function shown above and provides this value to the bus master to validate the transfer of data bytes.

Parametrics

Absolute maximum ratings:(1)voltage on any pin relative to ground:-0.5V to +6.0V;(2)operating temperature:-55℃ to +125℃;(3)storage temperature:-55℃ to +125℃;(4)soldering temperature:see J-STD-020A specification.

Features

Features:(1)unique 1-wire interface requires only one port pin for communication; (2)multidrop capability simplifies distributed temper-ature sensing applications; (3)requires no external components; (4)can be powered from data line. Power supply range is 3.0V to 5.5V; (5)zero standby power required; (6)measures temperatures from -55℃ to +125℃. Fahrenheit equivalent is -67°F to +257°F; (7)±0.5℃ accuracy from -10℃ to +85℃; (8)thermometer resolution is programmable from 9 to 12 bits; (9)converts 12-bit temperature to digital word in 750 ms (max.); (10)user-definable, nonvolatile temperature alarm settings; (11)Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition).
