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.

エンジニアコラム第19篇 EMC计算方法和EMC仿真（4）传导抗扰度（CI）的试行计算方法什么是IEC 62132-4 DPI法？大家好！我是ROHM的稻垣。
从本文开始将围绕“开关噪声-EMC”这一主题，对开关电源相关的EMC及其对策等进行解说。计划先介绍EMC相关的基础知识，然后再探讨噪声对策相关的内容。第一篇将以“何谓EMC”为题，先来熟悉EMC相关的术语，以此作为起点。
上一篇以“何谓EMC”为题对EMC的基础--EMC相关的术语意义进行了解说。本文将介绍“频谱基础”。作为基础内容，先简单介绍一下“何谓频谱？”。
最近在开发一款产品时，用到了一颗国产高精度ADC， 原子半导体的AS1412，了解到该产品的一些优势，不仅精度高、线性度好，功耗还低，能够满足很多力的传感测量，比如各种秤的应用、工业设备、仪器仪表等。
在电源模块应用中，EMC设计往往是重中之重，因为关乎整个用户产品的EMC性能。
首先看定义。定义主要按照问题性质，分为【电源、时钟CLK问题、地不平衡问题】。 再看原因分析： 针对三种问题，小编都有举例分析： 先看电源问题： 1. 排查手段 2. 问题分析 一般电源问题为DC-DC电路引起的器件（dcdc芯...
