DESCRIPTION

The DS1775 SOT23-5 Digital Thermometer and Thermostat provides temperature readings which indicate the temperature of the device. Thermostat settings and temperature readings are all communicated to/from the DS1775 over a simple 2–wire serial interface. No additional omponents are required; the device is truly a “ temperature–to–digital” converter.
