AD637JRZ

The AD637JRZ is a complete high accuracy monolithic rms-to-dc converter that computes the true rms value of any complex waveform. The features of AD637JRZ are: (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.

The following is about the absolute maximum ratings of AD637JRZ: (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°C to +150°C; (6)Lead Temperature Range (Soldering 10 secs): +300°C; (7)Rated Operating Temperature Range: 0°C to +70°C.

The electrical characteristics of the AD637JRZ are: (1)Total Error, Internal Trim: ±1 ± 0.5 mV ± % of Reading max; (2)TMIN to TMAX: ±3.0 ± 0.6 mV ± % of Reading max; (3)vs. Supply, + VIN = +300 mV: 30 V/V typ and 150 V/V max; (4)vs. Supply, VIN = 300 mV: 100 V/V typ and 300 mV/V max; (5)DC Reversal Error at 2 V: 0.25 % of Reading; (6)Nonlinearity 2 V Full Scale: 0.04 % of FSR; (7)Nonlinearity 7 V Full Scale: 0.05 % of FSR; (8)Total Error, External Trim: ±0.5 ± 0.1 mV ± % of Reading.
