Dallas Semiconductor Intros DS1626 Thermometer IC

Dallas Semiconductor Corp. (Dallas, TX) announced its new DS1626 three-wire digital thermometer and thermostat IC, which is available in a micro SOP package and is suitable for applications that require high precision in space-constrained environments. The thermometer function provides 9-bit, 10-bit, 11-bit or 12-bit digital temperature readings over the -55°C to +125°C temperature range, with ±0.5°C accuracy from 0°C to 70°C.

The DS1626 also has a thermostat functionality with non-volatile, user-defined trip points that allow the user to customize the threshold temperature and output hysteresis. It acts as a standalone thermostat, automatically measuring temperature upon power-up, and operating without processor or user intervention. Prices start at $1.66 for quantities of 1,000 and up.
