Dallas Semiconductor introduces the DS1626 high-precision 3-wire digital thermometer and thermostat. This is the first 3-wire ±0.5°C thermometer and standalone thermostat available in a µSOP package, which makes it ideal for applications that need high precision in a limited amount of space.
The DS1626 thermometer provides 9-, 10-, 11-, or 12-bit digital temperature readings over a -55°C to +125°C range, with ±0.5°C accuracy over a 0°C to +70°C range. It has thermostat functionality with nonvolatile (EEPROM) user-defined trip points that allow the user to customize 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. The DS1626 communicates through a standard 3-wire serial interface.
Typical applications for the DS1626 include thermostatic controls, industrial systems, consumer products, and thermometers. However, the DS1626's high accuracy and small size can benefit any space-constrained, thermally sensitive application. Prices start at $1.66 (1000-up, FOB USA).
