Texas Instruments TMP451 远程和 & 本地温度传感器
德州仪器 TMP451 远端&本地温度传感器是带有内置本地温度传感器的高准确度、小功率远端温度传感监测器。这类远程温度传感器通常通常采用低成本离散式 NPN 或 PNP 晶体管，或基板热晶体管。也可以是组成微处理器、微控制器或 FPGA 的二极管。本地和远程传感器的温度都以 12 位数码的形式显示, 分辨率为 0.0625°C。温度准确度在 ±本地和远程温度传感器典型的工作范围内为 1°C (最大值)。 双线串行接口接受 SMBus 通信协议。具有诸如串联电阻抵消、可编程非理想因子（η-factor）、可编程偏移、可编程温度界限和可编程数字滤波器等先进特点，是稳健的热监测解决方案，准确性、抗噪性更高。
Advanced features such as series resistance cancellation, programmable nonideality factor (η-factor), programmable offset, programmable temperature limits, and a programmable digital filter are combined to provide a robust thermal monitoring solution with improved accuracy and noise immunity. The TMP451-Q1 devices from Texas Instruments are AEC-Q100 qualified for automotive applications.
