DS1721S+T&R

The DS1721S+T&R is a 2 wire digital thermometer and thermostat in 8 pin NSOIC package. The 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 and allows for any hysteresis necessary. The active state of TOUT is configurable by the user.

• Supply voltage range is 2.7V to 5.5V
• Measures temperatures from -55°C to +125°C and fahrenheit equivalent is -67°F to +257°F
• Temperature resolution is configurable from 9 to 12 (default) bits (0.5°C to 0.0625°C resolution)
• Maximum conversion time (9bit resolution) of 93.75ms
