Product Summary

The AD637JRZ-RL is a RMS-to-DC Converter. The AD637JRZ-RL 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. A crest factor compensation scheme in the AD637JRZ-RL permits measurements of signals with crest factors of up to 10 with less than 1% additional error. The wide band-width of the AD637JRZ-RL permits the measurement of signals up to 600 kHz with inputs of 200 mV rms and up to 8 MHz when the input levels are above 1 V rms. As with previous monolithic rms converters from Analog Devices, Inc., the AD637JRZ-RL has an auxiliary dB output available to users. The logarithm of the rms output signal is brought out to a separate pin, allowing direct dB measurement with a useful range of 60 dB. An externally programmed reference current allows the user to select the 0 dB reference voltage to correspond to any level between 0.1 V and 2.0 V rms.
