DESCRIPTION  
The DS1721 2-Wire Digital Thermometer and Thermostat provides 12-bit temperature readings, which  
indicate the temperature of the device. Thermostatic settings and temperature readings are all  
communicated to/from the DS1721 over a simple 2-wire serial interface. No additional components are  
required; the device is truly a “temperature-to-digital” converter.  
The DS1721 has three address bits that allow a user to multidrop up to eight sensors along the 2-wire bus,  
greatly simplifying the bussing of distributed temperature sensing networks.  
The thermal alarm output, TOUT, is active when the temperature of the device exceeds a user-defined  
temperature TH. The output remains active until the temperature is equal to or below the user-defined  
temperature TL, allowing for any hysteresis necessary. The active state of TOUT is configurable by the  
user.  
For applications that require faster conversion times, the user can adjust the readout resolution from 12 to  
9 bits, effectively reducing the conversion time from 750ms (MAX) to 93.75 ms (MAX). This is  
particularly useful in applications where temperature changes large magnitudes very rapidly.  
Applications for DS1721 include personal computers/services, cellular telephones, office equipment, or  
any microprocessor-based, thermally sensitive system.
