Product Overview

The AD637JRZ is a High Precision Wideband 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 converters and comparable to discrete and modular techniques in accuracy, bandwidth and dynamic range. The converter 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 signal. A chip select connection on the AD637 permits the user to decrease the supply current from 2.2mA to 350µA during periods when the RMS function is not in use. This feature facilitates the addition of precision RMS measurement to remote or handheld applications where minimum power consumption is critical.
