DS18B20 Description

Short technical summary and product information.

The DS18B20 from Analog Devices is a versatile digital thermometer designed for precise temperature measurements. It utilizes a unique 1-Wire interface, requiring only a single data line for communication with a microprocessor, simplifying system design and reducing component count.

This device offers a wide operating temperature range of -55°C to +125°C, with an accuracy of ±0.4°C over the range of -10°C to +70°C. The thermometer's resolution is user-selectable, ranging from 9 to 12 bits, allowing for flexibility in applications requiring different levels of precision. It can also derive power directly from the data line, eliminating the need for an external power supply in certain configurations.

The DS18B20 features an alarm function with nonvolatile user-programmable upper and lower trigger points, enabling devices to identify and address temperature excursions outside set limits. Its unique 64-bit serial code allows multiple DS18B20s to operate on the same 1-Wire bus, making it suitable for distributed temperature sensing applications.

Available in a TO-92 package with a through-hole mounting style, the DS18B20 is well-suited for various applications including HVAC environmental controls, temperature monitoring systems, industrial equipment, and process control systems.
