General Description

The TMP451 device is a high-accuracy, low-power remote temperature sensor monitor with a built-in local temperature sensor.

The remote temperature sensors are typically low-cost discrete NPN or PNP transistors, or substrate thermal transistors or diodes that are integral parts of microprocessors, microcontrollers, or FPGAs.

The temperature is represented as a 12-bit digital code for both the local and remote sensors, giving a resolution of 0.0625°C.
