The DS18B20 is a digital thermometer IC that provides 9-bit to 12-bit Celsius temperature measurements. It communicates over a 1-Wire bus, requiring only a single data line for communication with a microprocessor. This simplifies distributed temperature sensing applications.
The device operates within a temperature range of -55°C to +125°C and offers an accuracy of ±0.4°C over the range of -10°C to +70°C. The resolution is user-selectable from 9 to 12 bits, and it can be powered directly from the data line (parasite power mode), eliminating the need for an external power supply. The operating voltage range is 2.5V to 5.5V.
Each DS18B20 has a unique 64-bit serial code, allowing multiple devices to function on the same 1-Wire bus. This feature is beneficial for applications such as HVAC environmental controls, temperature monitoring systems, and process control systems. The DS18B20 includes an alarm function with nonvolatile user-programmable upper and lower trigger points.
Available in a TO-92 package, the DS18B20 is suitable for through-hole mounting. Its robust design and versatile features make it ideal for various thermally sensitive applications.
