The Analog Devices Inc./Maxim Integrated DS1821T is an 8-bit digital temperature sensor designed for local temperature monitoring. This component operates across a -55°C to 125°C range with a typical accuracy of ±1°C under specified test conditions (0°C to 85°C). Utilizing the 1-Wire® interface, it offers efficient data communication. Key features include a one-shot conversion mode, an output switch for status indication, programmable limit settings, and a standby mode for power conservation. Supplied in a TO-220-3 package for through-hole mounting, the DS1821T is suitable for applications in industrial control, environmental monitoring, and consumer electronics where precise local temperature sensing is critical. The device operates from a 2.7V to 5.5V supply.
