Maxim Integrated DS1825U+T&R Product Overview

The DS1825U+T&R from Maxim Integrated is a high-precision, programmable digital thermometer and thermostat that offers an ideal solution for a wide range of temperature monitoring and control applications. This compact, versatile device comes in a convenient tape and reel (T&R) packaging format, which greatly facilitates automated assembly processes, making it a perfect choice for high-volume production.

At the heart of the DS1825U+T&R is a digital temperature sensor capable of providing a ±0.5°C accuracy over a wide temperature range of -10°C to +85°C. This precision is maintained over the entire power supply range of 3.0V to 5.5V. The device is also capable of operating over a broader temperature range from -55°C to +125°C with slightly reduced accuracy, making it suitable for extreme environmental conditions.

The DS1825U+T&R integrates a user-programmable nonvolatile (NV) alarm function with an external trigger. This allows the device to signal a microcontroller or other control system when the temperature exceeds user-defined thresholds, enabling automated temperature management within a system. The programmable resolution of the temperature readings, which can be set from 9 to 12 bits, provides flexibility in balancing the precision of the temperature data with the speed of acquisition.

Communication with the DS1825U+T&R is facilitated through a 1-Wire® interface, which minimizes the number of wires required for operation and allows for multiple devices to be connected in parallel on the same bus. This feature simplifies the design of complex systems that require multiple temperature sensing points while conserving valuable PCB space.

The device's small footprint is provided in an 8-pin µSOP package, which is ideal for space-constrained applications. The DS1825U+T&R’s robust design and high reliability make it an excellent choice for critical applications in industrial control, environmental monitoring, HVAC systems, and consumer electronics.

Maxim Integrated's commitment to quality ensures that the DS1825U+T&R meets the stringent requirements of modern electronic systems, providing designers with a reliable, high-performance temperature sensing solution.
