Product Summary

The AD737JRZ is a low power, precision, monolithic true rms-to-dcconverter. The AD737JRZ is laser trimmed to provide a maximum error of ±0.2 mV ±0.3% of reading with sine-wave inputs. Furthermore, the AD737JRZ maintains high accuracy while measuring a wide range ofinput waveforms, including variable duty cycle pulses and triac(phase) controlled sine waves. The low cost and small physicalsize of the AD737JRZ makes it suitable for upgrading the per-formance of non-rms precision rectifiers in many applications.Compared to these circuits, the AD737JRZ offers higher accuracy atequal or lower cost.
