The AD637JQ is a high accuracy true RMS-to-DC converter from Analog Devices, designed for precision AC measurement applications. It offers 0.02% maximum nonlinearity for input signals from 0 V to 2 V rms, ensuring accurate conversion over a wide dynamic range. The device provides 8 MHz bandwidth at 2 V rms input and 600 kHz at 100 mV rms, accommodating both high-level and low-level signals. It includes crest factor compensation up to 3 with only 0.1% additional error, making it suitable for measuring waveforms with high crest factors. The quiescent current is typically 2.2 mA, which can be reduced to 350 µA via the chip select pin, enabling power savings in battery-operated systems. The operating voltage range is ±3V to ±18V, allowing flexible integration into various power supply designs. This converter is ideal for high-precision instrumentation, audio analysis, and data acquisition systems requiring accurate RMS measurement.
