General Description
The DS1775 digital thermometer and thermostat provides temperature readings that indicate the device’s temperature. Thermostat settings and temperature readings are all communicated to/from the DS1775 over a simple 2-wire serial interface. No additional components are required; the device is truly a “temperature-to-digital” converter.
