1. The AD637 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 since it relates directly to the power of the signal. The rms value of a statistical signal is also related to the standard deviation of the signal.


Supply voltage: ± 3V to ± 18V DC
Bandwidth: 8 MHz (2 V rms input)
                        600 kHz (100 mV rms input)

Detection accuracy: 0.02% maximum non-linearity, 0 V to 2 V rms input crest factor is 3 .Additional error 0.10%
Computational objects: True RMS,Squared value,Mean-square value,Absolute value

Dynamic range: dB output (60 dB range)
Buffered output short circuit J4 \ J7, output from BUFF OUT
