The AD637BR 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 in accuracy, bandwidth, and dynamic range.
Key features include a maximum nonlinearity of 0.02% for inputs from 0 V to 2 V rms, and a wide bandwidth of 8 MHz at 2 V rms input, extending to 600 kHz at 100 mV rms input. It supports crest factors up to 10 with less than 1% additional error and provides a 60 dB dB output range.
This IC 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.
The AD637BR is available in a 16-SOIC surface mount package. It operates with supply voltages from ±3V to ±18V and has a quiescent current of 2.2 mA, which can be reduced to 350 µA using the chip select feature for power-sensitive applications.
