Contextual Info: National Semiconductor Linear Brief 25 June 1973 Introduction 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. Further, since the input is DC coupled, it can provide the true rms equivalent of a DC and AC signal.
