AD637 Datasheet | Analog Devices

Data Sheet Features 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 k Hz at 100 m V rms putes True rms Square Mean square Absolute value d B output (60 d B range) Chip select/power-down feature allows Analog three-state operation Quiescent current reduction from 2.2 m A to 350 µA GENERAL DESCRIPTION The AD637 is a plete, high accuracy, rms-to-dc converter that putes the true rms value of any plex waveform. It offers performance that is unprecedented in integrated circuit rms-to-dc converters and parable to discrete and modular techniques in accuracy, bandwidth, and dynamic range. The AD637 putes the true root mean square, mean square, or absolute value of any plex 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...
