AD536AKD集成电路（IC）的RMS至DC转换器规格书PDF中文资料

AD536AKD属于集成电路（IC）的RMS至DC转换器。由亚德诺半导体技术有限公司制造生产的AD536AKDRMS 至 DC 转换器RMS 至 DC 转换器产品族中的产品可用于执行测量时变波形的数学功能，并返回一个与等效稳态 (DC) 值成比例的值，如果将其应用于电阻负载，则会产生相同的功率耗散。这些转换器通常用于交流电源相关应用中的测量，它们之间以及它们与用于类似终端的其他技术之间的区别在于输入为非正弦波形时所给出结果的准确性。

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.
