The TMP421AIDCNR from Texas Instruments is a versatile digital temperature sensor designed for accurate temperature monitoring. It integrates both a local temperature sensor and the capability to monitor remote temperatures, typically from diode-connected transistors in microcontrollers or processors.
This sensor operates across a wide temperature range of -40°C to 125°C, with a sensing temperature range from -64°C to 191°C. It offers a high resolution of 11 bits and an accuracy of ±1.5°C for remote sensing and ±2.5°C for local sensing under specified conditions. The device communicates using the I2C and SMBus serial interfaces, supporting multiple addresses and featuring one-shot conversion.
Available in a compact SOT-23-8 package, the TMP421AIDCNR is suitable for surface mount applications. Its features include series resistance cancellation and n-factor correction, enhancing measurement accuracy. The device operates from a supply voltage of 2.7V to 5.5V and has a maximum supply current of 38µA, making it an energy-efficient choice for various electronic designs.
