Digital Temperature Sensor
The DS1631 provides 9-, 10-, 11-, or 12-bit digital temperature readings over a -55 degrees Celsius to +125 degrees Celsius range, with ±0.5 degrees Celsius accuracy over a 0 degrees Celsius to +70 degrees Celsius range. It has thermostat functionality with nonvolatile (EEPROM) user-defined trip points that allow the user to customize the threshold temperature and output hysteresis. Communication with the DS1631 is achieved through a standard 2-wire serial interface.
Typical applications for the DS1631 include network routers and switches, cellular base stations, and portable products; however, the DS1631's high accuracy and small size can benefit any space-constrained, thermally sensitive application.
