RMS is a fundamental measurement of an ac signal. RMS to DC converters manufactured by ADI are used in a wide variety of applications where precision, low power measurement of ac signal is the prime objective. An ADI RMS-to-DC converter offers 'real time' measurements, i.e. 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-DC converters optimized for the most demanding performance, power and cost applications satisfying True RMS needs.
A brief introduction on the technology and its applications, please refer to the on line multimedia module Introduction to Analog RMS-to-DC Technology: Converters and Applications.
