Texas Instruments TMP468高精度温度传感器
Texas Instruments TMP468高精度温度传感器是一款多区域、高精度、低功耗温度传感器。该传感器采用2线、SMBus或I2C兼容接口。不但能监测本地温度，还可同时监测多达八个远程二极管连接的温度区域。
Aggregating the temperature measurements across a system allows improved performance through tighter guard bands and reduces board complexity. A typical use case is for monitoring the temperature across different processors like MCUs, GPUs, and FPGAs in complex systems.
These systems include servers and telecommunications equipment. Advanced features like series resistance cancellation, programmable non-ideality factor, programmable offset, and programmable temperature limits are included in the Texas Instruments TMP468 to provide a robust thermal monitoring solution with improved accuracy and noise immunity.
