RMS to DC Converters

RMS-to-DC converters manufactured by Analog Devices are used in a wide variety of applications where precision and low power measurement of ac signals is the prime objective. An ADI rms-to-dc converter offers real time measurements, meaning there are no latency issues such as those that limit the frequency response of other technologies—the dc output is simply the equivalent of the rms input, over a wide range of input frequencies, and for complex waveforms not limited to sine waves. ADI offers a wide range of rms-to-dc converters optimized for the most demanding performance, power, and cost applications satisfying true rms needs.
