AD637JQ - Brand New Analog Devices RMS-to-DC Converters
-
Description
The AD637JQ is a complete, high accuracy, rms-to-dc converter that computes the true rms value of any complex waveform. It offers unprecedented performance in integrated circuit rms-to-dc converters, comparable to discrete and modular techniques in accuracy, bandwidth, and dynamic range. The AD637JQ computes the true root mean square, mean square, or absolute value of any complex ac (or ac plus dc) input waveform and provides an equivalent dc output voltage. The true rms value of a waveform is more useful than an average rectified signal as it directly relates to the power of the signal. The rms value of a statistical signal corresponds to the standard deviation of the signal.
Specifications and 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 kHz at 100 mV rms. Computes true rms, square, mean square, absolute value, and 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.
Application Scenarios
The AD637JQ is widely used in various applications where accurate measurement of rms values is required. It is commonly used in power monitoring and control systems, audio equipment, instrumentation, signal processing, communication systems, and more. Its high accuracy and wide bandwidth make it suitable for a range of complex waveform analysis.
Comparison
