3-wire digital thermometer and thermostat

12 February 2003 News

Dallas Semiconductor's DS1626 high-precision 3-wire digital thermometer and thermostat is claimed to be the first 3-wire ±0,5°C thermometer and standalone thermostat available in microSOP package. The DS1626 thermometer provides 9-, 10-, 11-, or 12-bit digital temperature readings over a -55 to +125°C range, (±0,5°C accuracy over 0 to +70°C). It has thermostat functionality with nonvolatile (EEPROM) user-defined trip points that allow the user to customise the threshold temperature and output hysteresis. The DS1626 acts as a stand-alone thermostat, automatically measuring temperature upon power-up and operating without processor or user intervention. It communicates through a standard 3-wire serial interface. Typical applications include thermostatic controls, industrial systems, consumer products, and thermometers.
