It computes the true RMS (Root Mean Square) value of an AC input signal and provides a DC output voltage proportional to the RMS input. The core uses a proprietary delta-sigma demodulator architecture: the input signal is first squared by a Gilbert cell multiplier, then fed into a delta-sigma modulator that converts the squared signal into a 1-bit stream. The output low-pass filter (a single external capacitor on the OUT pin) extracts the DC component (average of the squared signal), and an internal square-root circuit produces the RMS result. This approach is more accurate than the log-antilog method used in older RMS-to-DC converters (AD736) because it eliminates the temperature drift of the log\/antilog circuits. The 500kHz bandwidth allows measurement of signals up to 500kHz at +\/-1% accuracy. The single-capacitor output filter simplifies design: a 1uF capacitor provides 0.01% ripple at 60Hz. The EN pin (active HIGH, internal pull-up) disables the device to reduce current from 350uA to 0.1uA. Applications include AC voltage measurement, power metering, and audio level detection.","pin_description":"
