DS1721 Digital Thermometer And Thermostat

The DS1721 digital thermometer and thermostat features 1C accuracy over a -10C to +85C range. Thermometer data is read out over a 2-wire serial bus in 2's complement format with 9 to 12 bits of resolution (user-programmable). The DS1721 features three address inputs, allowing users to multidrop up to eight DS1721 devices on one bus.
The DS1721 offers thermostatic functionality with over-temperature (TH) and under-temperature (TL) user-programmable trip-points stored in on-chip SRAM The two trip-points provide programmable thermostat hysteresis: the thermostat output is asserted when the measured temperature exceeds TH and it remains active until the temperature falls below TL.
The DS1721 is available in 150mil 8-pin SO DS1721S and 8-pin MAX/SOP DS1721U packages. For applications requiring higher precision, the DS1631 provides 0.5C accuracy and is functionally compatible with the DS1721.
