Product description
Digital Thermometer and Thermostat
The DS1620+ Digital Thermometer and Thermostat provides 9-bit temperature readings which indicate the temperature of the device. With three thermal alarm outputs, the DS1620+ can also act as a thermostat. THIGH is driven high if the DS1620's temperature is greater than or equal to a user-defined temperature TH. TLOW is driven high if the DS1620+'s temperature is less than or equal to a user-defined temperature TL. TCOM is driven high when the temperature exceeds TH and stays high until the temperature falls below that of TL.
Features
* Requires no external components
* Supply voltage range covers from 2.7V to 5.5V
* Measures temperatures from -55°C to +125°C in 0.5°C increments
* Temperature is read as a 9-bit value
* Converts temperature to digital word in 750ms (max)
* Thermostatic settings are user-definable and nonvolatile
* Data is read from/written via a 3-wire serial interface (CLK, DQ, RST )
* Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
