Product Summary

The AD736AR is a low power, precision, monolithic true rms-to-dc converter. It is laser trimmed to provide a maximum error of ± 0.3mV ± 0.3% of reading with sine-wave inputs. Furthermore, the AD736AR maintains high accuracy while measuring a wide range of input waveforms, including variable duty cycle pulses and triac (phase) controlled sine waves. The low cost and small physical size of this converter make AD736AR suitable for upgrading the performance of non-rms precision rectifiers in many applications.
