Programmable limit and resolution, plus one-shot and standby modes, let the host controller wake the sensor, take a reading, and return to low-power sleep — useful in battery-powered loggers where every microamp counts. Supplied on Tape & Reel (TR) or Cut Tape (CT), the reel format is the standard for pick-and-place assembly — the CT option works for prototype runs or small-batch builds where a full reel is overkill.","metaTitle":"DS1721U+T&R Analog Devices Temp Sensor, I²C, -55°C to 125°C","metaDescription":"DS1721U+T&R digital temperature sensor from Analog Devices.
