TMP451 Datasheet PDF

●DESCRIPTION

●The TMP451 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.

●FEATURES

●• ±1°C Accuracy for Local and Remote Diode Sensors

●• 0.0625°C Resolution for Local and Remote Channels

●• 1.7-V to 3.6-V Supply and Logic Voltage Range

●• 27-µA Operating Current, 3-µA Shutdown Current
