Product Overview

The AD637JQ is a complete, high accuracy, RMS-to-DC Converter that computes the true rms value of any complex waveform. It offers performance that is unprecedented in integrated circuit RMS-to-DC converter and comparable to discrete and modular techniques in accuracy, bandwidth and dynamic range. This computes the true root mean square, mean square or absolute value of any complex AC (or AC plus DC) input waveform and gives an equivalent dc output voltage. The true rms value of a waveform is more useful than an average rectified signal because it relates directly to the power of the signal. The rms value of a statistical signal relates to the standard deviation of the signal. Superior crest factor compensation permits measurements of signals with crest factors of up to 10 with less than 1% additional error.
  • High accuracy
  • Wide bandwidth
  • 60dB Output range
  • Analogue 3-state operation
  • 2.2mA to 350µA Quiescent current reduction
