The DS1820 from Dallas Semiconductor is a digital thermometer that provides 9-bit temperature readings. Its key feature is the unique 1-Wire interface, which requires only a single port pin for communication, simplifying system design and reducing component count. This interface also allows for multidrop capability, enabling distributed temperature sensing applications.
The device can measure temperatures ranging from -55°C to +125°C with a resolution of 0.5°C increments. It can be powered directly from the data line, eliminating the need for an external power source in many applications. The DS1820 also includes user-definable, nonvolatile temperature alarm settings.
Packaged in a TO-226-3 case, the DS1820 is suitable for through-hole mounting. Its applications include thermostatic controls, industrial systems, consumer products, and any thermally sensitive system requiring accurate temperature monitoring.
