TMP451/TMP451-Q1 Remote/Local Temperature Sensors

Texas Instruments TMP451/TMP451-Q1 Remote and Local Temperature Sensors are high-accuracy, low-power remote temperature sensor monitors with a built-in local temperature sensor. The remote temperature sensors are typically low-cost discrete NPN or PNP transistors, or substrate thermal transistors. They can also be 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. The temperature accuracy is ±1°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.
