SLOS877 – OCTOBER 2014 TMP451-Q1 ±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-Q1 device is a high-accuracy, lowpower 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 the 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 twowire
serial
interface
accepts
