AD736 Datasheet (Analog Devices) - True RMS-to-DC Converter

AD736, True RMS-to-DC Converter

The AD736 is a low power, precision, monolithic true rms-todc converter.

It is laser trimmed to provide a maximum error of ±0.3 mV ± 0.3% of reading with sine wave inputs.

Furthermore, it maintains high accuracy while measuring a wide range of input waveforms, including variable duty-cycle pulses an
