AD536A屬于集成電路（IC）的RMS至DC轉(zhuǎn)換器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD536ARMS 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)行測量時變波形的數(shù)學功能，并返回一個與等效穩(wěn)態(tài) (DC) 值成比例的值，如果將其應用于電阻負載，則會產(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)應用中的測量，它們之間以及它們與用于類似終端的其他技術(shù)之間的區(qū)別在于輸入為非正弦波形時所給出結(jié)果的準確性。

GENERAL DESCRIPTION

The AD536A is a complete monolithic integrated circuit that performs true rms-to-dc conversion. It offers performance comparable or superior to that of hybrid or modular units costing much more. The AD536A directly computes the true rms value of any complex input waveform containing ac and dc components.

A crest factor compensation scheme allows measurements with 1 error at crest factors up to 7. The wide bandwidth of the device extends the measurement capability to 300 kHz with less than 3 dB errors for signal levels greater than 100 m V.
