AD637 - Wide-Band RMS-to-DC Converter

Analog Devices

Datasheet Details

The AD637 is a complete, high accuracy, rms-to-dc converter that computes the true rms value of any complex waveform.

High accuracy 0.02% maximum nonlinearity, 0 V to 2 V rms input 0.1% additional error to crest factor of 3 Wide bandwidth 8 MHz at 2 V rms input 600 kHz at 100 mV rms Computes True rms Square Mean square Absolute value dB output (60 dB range) Chip select/power-down feature allows Analog three-state operation Quiescent current reduction from 2.2 mA to 350 µA.
