Linear Technology LTC1968
the LTC1968 proprietary architecture, when compared to conventional log-antilog RMS-to-DC converters, are higher linearity and accuracy, bandwidth independent of amplitude and improved temperature behavior. The LTC1968 operates with single-ended or differential input signals and accurately supports crest factors up to 4. The LTC1968 allows hassle-free system calibration at any input voltage.FEATURES
