Product Summary

The AD637ARZ is a complete high accuracy monolithic rms-to-dc converter that computes the true rms value of any complex waveform. The AD637ARZ 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 AD637ARZ permits measurements of signals with crest factors of up to 10 with less than 1% additional error.

Parametrics

AD637ARZ absolute maximum ratings: (1)ESD Rating: 500 V; (2)Supply Voltage: ±18 V dc; (3)Internal Quiescent Power Dissipation: 108 mW; (4)Output Short-Circuit Duration: Indefinite; (5)Storage Temperature Range: –65℃ to +150℃; (6)Lead Temperature Range (Soldering 10 secs): +300℃; (7)Rated Operating Temperature Range: –40℃ to +85℃.

Features

AD637ARZ features: (1)High Accuracy: 0.02% Max Nonlinearity, 0 V to 2 V RMS Input, 0.10% Additional Error to Crest Factor of 3; (2)Wide Bandwidth: 8 MHz at 2 V RMS Input, 600 kHz at 100 mV RMS; (3)Computes: True RMS, Square, Mean Square, Absolute Value; (4)dB Output (60 dB Range); (5)Chip Select-Power Down Feature Allows: Analog “3-State” Operation, Quiescent Current Reduction from 2.2 mA to 350 mA; (6)Side-Brazed DIP, Low Cost Cerdip and SOIC.
