The EMC1412 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model including 45nm, 65nm and 90nm processors) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications.
The EMC1412 monitors two temperature channels (one external and one internal). It provides ±1°C accuracy for both external and internal diode temperatures.
Resistance Error Correction automatically eliminates the temperature error caused by series resistance allowing greater flexibility in routing thermal diodes. Beta Compensation eliminates temperature errors caused by low, variable beta transistors common in today's fine geometry processors. The automatic beta detection feature monitors the external diode/transistor and determines the optimum sensor settings for accurate temperature measurements regardless of processor technology. This frees the user from providing unique sensor configurations for each temperature monitoring application. These advanced features plus ±1° measurement accuracy provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications.

從本文開始將圍繞“開關(guān)噪聲-EMC”這一主題，對開關(guān)電源相關(guān)的EMC及其對策等進(jìn)行解說。計(jì)劃先介紹EMC相關(guān)的基礎(chǔ)知識，然后再探討噪聲對策相關(guān)的內(nèi)容。第一篇將以“何謂EMC”為題，先來熟悉EMC相關(guān)的術(shù)語，以此作為起點(diǎn)。
上一篇以“何謂EMC”為題對EMC的基礎(chǔ)--EMC相關(guān)的術(shù)語意義進(jìn)行了解說。本文將介紹“頻譜基礎(chǔ)”。作為基礎(chǔ)內(nèi)容，先簡單介紹一下“何謂頻譜？”。
最近在開發(fā)一款產(chǎn)品時，用到了一顆國產(chǎn)高精度ADC， 原子半導(dǎo)體的AS1412，了解到該產(chǎn)品的一些優(yōu)勢，不僅精度高、線性度好，功耗還低，能夠滿足很多力的傳感測量，比如各種秤的應(yīng)用、工業(yè)設(shè)備、儀器儀表等。
在電源模塊應(yīng)用中，EMC設(shè)計(jì)往往是重中之重，因?yàn)殛P(guān)乎整個用戶產(chǎn)品的EMC性能。
? ? 首先看定義。定義主要按照問題性質(zhì)，分為【電源、時鐘CLK問題、地不平衡問題】。 再看原因分析： 針對三種問題，小編都有舉例分析： 先看電源問題： 1. 排查手段 2. 問題分析 一般電源問題為DC-DC電路引起的器件（dcdc芯...
