AD637J集成電路（IC）的RMS至DC轉換器規(guī)格書PDF中文資料

AD637J屬于集成電路（IC）的RMS至DC轉換器。由亞德諾半導體技術有限公司制造生產的AD637JRMS 至 DC 轉換器RMS 至 DC 轉換器產品族中的產品可用于執(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，則會產生相同的功率耗散。這些轉換器通常用于交流電源相關應用中的測量，它們之間以及它們與用于類似終端的其他技術之間的區(qū)別在于輸入為非正弦波形時所給出結果的準確性。

PRODUCT DESCRIPTION

The AD637 is a complete high accuracy monolithic rms-to-dc converter that computes the true rms value of any complex waveform. It offers performance that is unprecedented in integrated circuit rms-to-dc converters and comparable to discrete and modular techniques in accuracy, bandwidth and dynamic range. A crest factor compensation scheme in the AD637 permits measurements of signals with crest factors of up to 10 with less than 1 additional error. The circuit’s wide bandwidth permits the measurement of signals up to 600 kHz with inputs of 200 mV rms and up to 8 MHz when the input levels are above 1 V rms.
