The EMC1053 is a System Management Bus (SMBus) temperature sensor that monitors three temperature zones, one internal diode and two externally connected diodes, for PC and embedded environments. The EMC1053 includes resistance error correction and ideality factor configuration to eliminate major sources of temperature measurement error1.
An added feature to the EMC1053 is a function that automatically compares the two external temperature zones and reports the hotter of the two temperatures. Selectable conversion rates and standby mode support low-power operation. The temperature measurement ranges support two data ranges (and formats), -64°C to +127°C and -64°C to +191°C.

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？”。
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及其對策等進行解說。計劃先介紹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。
今天就給大家分享下典型EMC三問，希望對各位小伙伴有所幫助，如您有遇到EMC問題，也可以在公眾號對話框給我們留言哦，我們會針對典型的EMC問題進行回復(fù)。
EMC問題越早考慮、越早解決，費用越小、效果越好。在新產(chǎn)品研發(fā)階段就進行EMC設(shè)計，比等到產(chǎn)品EMC測試不合格才進行改進，費用可以大大節(jié)省，效率可以大大提高；反之，效率就會大大降低，費用就會大大增加。
