Product Summary

The AD637JR is a complete high accuracy monolithic rms-to-dc converter that computes the true rms value of any complex waveform. The AD637JR offers performance that is unprecedented in inte-grated 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 AD637JR per-mits measurements of signals with crest factors of up to 10 with less than 1% additional error. The circuit wide bandwidth per-mits 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.
