Texas Instruments TMP421AIDCNRG4 is a digital, local/remote temperature sensor designed for precise thermal monitoring. This device offers a broad operating temperature range of -40°C to 125°C for local sensing and -64°C to 191°C for remote sensing. Key features include one-shot conversion, an output switch, programmable limit functionality, and a shutdown mode, enhancing system flexibility and power management. The sensor provides an 11-bit resolution, delivering accurate temperature readings with a typical accuracy of ±1.5°C and a maximum of ±2.5°C across specified test conditions.
Utilizing the SMBus interface for communication, the TMP421AIDCNRG4 is housed in an 8-lead SOT-23 package, suitable for surface mounting. The device operates from a supply voltage range of 2.7V to 5.5V. This component is frequently employed in industrial automation, consumer electronics, and computing applications where reliable temperature monitoring is critical. It is supplied in Tape & Reel (TR) packaging.
