The HT18B20A is a programmable resolution 1-Wire digital thermometer compatible with the DS18B20. It offers 9-bit to 12-bit Celsius temperature measurements with a user-programmable alarm function. Communicating via a single data line, it can also derive power directly from the data line (parasite power), eliminating the need for an external power supply. Each HT18B20A features a unique 64-bit serial code, enabling multiple devices on the same 1-Wire bus. This makes it suitable for applications such as HVAC environmental controls, building and equipment temperature monitoring, and process monitoring systems.
