DS1721 Thermometer and Thermostat Series Datasheet

The DALLAS SEMICONDUCTOR (MAXIM) 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.
