Maxim Integrated DS18B20-PAR+T&R Programmable Resolution 1-Wire Digital Thermometer

The DS18B20-PAR+T&R from Maxim Integrated is a highly reliable and precise digital thermometer that provides 9-bit to 12-bit Celsius temperature measurements. It communicates over a 1-Wire bus that requires only one data line (and ground) for communication with a central microprocessor. The DS18B20-PAR+T&R variant is particularly notable for its parasite power mode, which allows the device to draw power directly from the data line, eliminating the need for an external power supply.

This versatile sensor offers an adjustable resolution feature, allowing users to optimize the balance between measurement resolution and conversion time. This can be particularly useful in systems where either quick temperature readings or high precision is required. The DS18B20-PAR+T&R 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, providing dependable and accurate temperature readings for a wide range of applications.

One of the key features of the DS18B20-PAR+T&R is its ability to operate on a network. Each sensor has a unique 64-bit serial code, which allows multiple DS18B20-PAR+T&R devices to function on the same 1-Wire bus. This feature simplifies the design of a temperature control system and reduces the complexity of the wiring, making it ideal for environmental monitoring, HVAC systems, and temperature regulation within electronics.

The DS18B20-PAR+T&R comes in a compact TO-92 package and is available in tape and reel form, making it suitable for automated assembly processes. This ease of integration, combined with its low power consumption and robust feature set, makes it an excellent choice for a broad array of applications, including industrial systems, consumer products, and thermally sensitive systems.

Maxim Integrated's commitment to quality ensures that the DS18B20-PAR+T&R digital thermometer meets the highest standards of reliability and performance, providing designers and engineers with a trusted solution for their temperature sensing needs.
