Product Summary

The AD637JQ is a complete, high accuracy, monolithic rms-to-dc converter that 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 AD637JQ permits measurements of signals with crest factors of up to 10 with less than 1% additional error. The wide band-width of the AD637JQ 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.

Parametrics

AD637JQ 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 (Soldering 10 sec): 300℃; (7)Rated Operating Temperature Range: 0℃ to 70℃.

Features

AD637JQ features: (1)High accuracy: 0.02% maximum 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 three-state operation, Quiescent current reduction from 2.2 mA to 350 μA; (6)14-lead SBDIP, 14-lead low cost CERDIP, and 16-lead SOIC_W.
