The AD637BRZ from Analog Devices is a complete, high-accuracy RMS-to-DC converter designed to compute the true RMS value of any complex waveform. It offers performance comparable to discrete and modular techniques, providing unprecedented accuracy, bandwidth, and dynamic range in an integrated circuit.
Key features include a maximum nonlinearity of 0.02% for inputs from 0 V to 2 V rms and a wide bandwidth of up to 8 MHz at 2 V rms input, or 600 kHz at 100 mV rms input. The device also offers superior crest factor compensation, allowing measurements of signals with crest factors up to 10 with less than 1% additional error. A direct dB output with a 60 dB range is also available.
The AD637BRZ computes the true root mean square, mean square, or absolute value of AC or AC plus DC input waveforms, providing an equivalent DC output voltage. The true RMS value is directly related to signal power, making it more useful than an average rectified signal for statistical analysis.
Packaged in a 16-SOIC (0.295" width) surface-mount package, the AD637BRZ operates with a voltage range of ±3V to 18V and a quiescent current of 2.2 mA. It features a chip select/power-down function that reduces supply current to 350 µA when not in use, facilitating low-power applications. The input circuitry is protected from overload voltages.
