The AD637JRZ from Analog Devices is a high-accuracy, wideband RMS-to-DC converter designed to compute the true RMS value of complex AC or AC plus DC input waveforms. It offers exceptional performance with a maximum nonlinearity of 0.02% and a wide bandwidth of up to 8 MHz at 2 V rms input, or 600 kHz at 100 mV rms input.
This converter computes the true root mean square, mean square, or absolute value, providing an equivalent DC output voltage. It features superior crest factor compensation, allowing measurements of signals with crest factors up to 10 with less than 1% additional error. A dedicated pin provides a direct dB value of the RMS output with a 60 dB range.
The AD637JRZ is available in a 16-SOIC package and supports surface mount installation. It operates with supply voltages from ±3V to ±18V and has a quiescent current that can be reduced from 2.2 mA to 350 µA via a chip select pin, making it suitable for power-sensitive applications. The device is laser wafer trimmed, requiring only an external capacitor to set the averaging period.
