Product Summary

The DS18B20Z+ is a Digital Thermometer. It provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20Z+ over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to the DS18B20Z+. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.

Parametrics

DS18B20Z+ 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

DS18B20Z+ features: (1)Unique 1-Wire interface requires only one port pin for communication; (2)Multidrop capability simplifies distributed temperature 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); (12)Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system.
