Analog Devices Inc./Maxim Integrated DS1821 is a digital temperature sensor designed for local sensing applications. This component operates across a wide temperature range of -55°C to 125°C, with a specified accuracy of ±1°C under typical test conditions (0°C to 85°C). It features an 8-bit resolution for temperature readings and utilizes the 1-Wire® communication protocol for simplified interfacing. The DS1821 supports features such as one-shot temperature conversion, an output switch, programmable temperature limits, and a standby mode to conserve power. Supplied in a TO-92-3 package for through-hole mounting, this device is suitable for applications in industrial automation, consumer electronics, and automotive systems requiring precise local temperature monitoring.
