True rms detector

Posted on Sep 19, 2012

The circuit will provide a dc output equal to the rms value of the input. Accuracy is typically 2% for a 20 Vpp input signal from 50 Hz to 100 kHz, although it`s usable to about 500 kHz. The lower frequency is limited by the size of the filter capacitor

Since the input is dc coupled, it can provide the true rms equivalent of a dc and ac signal.
