SBOS686A – JUNE 2013 – REVISED DECEMBER 2014 TMP451 ±1°C Remote and Local Temperature Sensor With Π-Factor and Offset Correction,
Series-Resistance Cancellation, and Programmable Digital Filter
1 Features 3 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 0.0625В°C.
The temperature accuracy is В±1В°C (maximum) in the
typical operating range for the local and the remote
temperature sensors. The two-wire serial interface
accepts the SMBus communication protocol. 1 В±1В°C Accuracy for Local and Remote Diode
