AD636J屬于集成電路（IC）的RMS至DC轉(zhuǎn)換器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD636JRMS 至 DC 轉(zhuǎn)換器RMS 至 DC 轉(zhuǎn)換器產(chǎn)品族中的產(chǎn)品可用于執(zhí)行測(cè)量時(shí)變波形的數(shù)學(xué)功能，并返回一個(gè)與等效穩(wěn)態(tài) (DC) 值成比例的值，如果將其應(yīng)用于電阻負(fù)載，則會(huì)產(chǎn)生相同的功率耗散。這些轉(zhuǎn)換器通常用于交流電源相關(guān)應(yīng)用中的測(cè)量，它們之間以及它們與用于類(lèi)似終端的其他技術(shù)之間的區(qū)別在于輸入為非正弦波形時(shí)所給出結(jié)果的準(zhǔn)確性。

GENERAL DESCRIPTION

The AD636 is a low power monolithic IC that performs true rms-to-dc conversion on low level signals. It offers performance that is comparable or superior to that of hybrid and modular converters costing much more. The AD636 is specified for a signal range of 0 mV to 200 mV rms. Crest factors up to 6 can be accommodated with less than 0.5 additional error, allowing accurate measurement of complex input waveforms.
