ANALOG DEVICES AD8436: Low Cost Low Power True RMS-to-DC Converter Data Sheet (Rev A 2012-07-18-)
The AD8436 is a translinear precision, low-power true RMS-to-DC converter designed to compute the precise DC equivalent of the RMS value of AC waveforms. It is suitable for complex patterns such as those generated by switch-mode power supplies and triacs. The device features a wide dynamic input range from 100 pV RMS to 3 V RMS and delivers true RMS results at a lower cost than digital or peak-averaging solutions.
