DALLAS Semiconductor, represented by Arrow Electronics , has introduced 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 microSOP 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.
