The Texas Instruments TMP422AIDCNT is a digital, local/remote temperature sensor designed for precision monitoring across a wide operating range of -40°C to 125°C. This component features an 11-bit resolution, providing granular temperature readings. Its SMBus output interface ensures efficient data transfer. The TMP422AIDCNT supports both local and remote temperature sensing, with the local sensing range mirroring the operating temperature and the remote sensing capable of measuring from -64°C to 191°C. Key features include a one-shot conversion mode, an output switch, programmable limit functionality, and a shutdown mode for power management. This sensor is supplied in a SOT-23-8 package, suitable for surface mount applications. Its accuracy specifications are ±1.5°C (typical) and ±2.5°C (maximum) within its operating temperature range. The device operates from a supply voltage of 2.7V to 5.5V and is commonly utilized in industrial, medical, and automotive applications requiring robust thermal management. The TMP422AIDCNT is provided on tape and reel.
