DS18B20+PAR Programmable Resolution 1-Wire Digital Thermometer

The DS18B20+PAR from Maxim Integrated is a highly reliable, programmable resolution 1-Wire digital thermometer that offers the convenience of over-the-bus power. This innovative device provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device itself.

With its unique 1-Wire interface, the DS18B20+PAR allows for communication with a central microprocessor with minimal wiring, making it ideal for a wide range of temperature monitoring applications. Its parasitic power mode enables the device to draw power directly from the data line, reducing the need for an external power supply and simplifying the system design.

The DS18B20+PAR is capable of measuring temperatures from -55°C to +125°C (-67°F to +257°F) with ±0.5°C accuracy from -10°C to +85°C. This precision makes it suitable for various critical applications, including environmental control, food processing, HVAC systems, and more.

Each DS18B20+PAR has a unique 64-bit serial code, which allows multiple sensors to function on the same 1-Wire bus. This feature is particularly beneficial for systems that require the monitoring of temperature at multiple points.

Key features of the DS18B20+PAR include:

• Unique 1-Wire interface requires only one port pin for communication
• Parasitic power mode allows operation without an external power supply
• Multiple sensors can be connected on the same bus
• User-definable nonvolatile (NV) alarm settings
• Highly accurate temperature readings with configurable resolution
• Compact and versatile design for easy integration into a variety of systems

For those looking to integrate the DS18B20+PAR into their systems, Maxim Integrated provides comprehensive support, including detailed datasheets, application notes, and a dedicated support team to assist with any technical queries.

Whether you're developing a sophisticated climate control system or simply need to monitor temperature within a home project, the DS18B20+PAR presents a reliable and efficient solution for digital temperature sensing needs.
