The LTC1966 is a true RMS-to-DC converter that uses a DS computational technique to make it dramatically simpler to use, significantly more accurate, lower in power consumption and more flexible than conventional logantilog RMS-to-DC converters. The LTC1966 RMS-to-DC converter has an input signal range from 5mVRMS to 1.5VRMS (a 50dB dynamic range with a single 5V supply rail) and a 3dB bandwidth of 800kHz with signal crest factors up to four.
