The AD737JRZ from Analog Devices is a low-power, precision, monolithic true RMS-to-DC converter. It is designed to compute the RMS value of both AC and DC input voltages, offering high accuracy with a maximum error of ±0.2 mV ± 0.3% of reading for sine wave inputs. This device maintains accuracy for a wide range of input waveforms, including variable duty cycle pulses and phase-controlled sine waves, with signal crest factors up to 5.
With a wide power supply range of ±2.5 V to ±16.5 V and low power consumption, the AD737JRZ is optimized for battery-powered applications such as portable multimeters. It features a high input impedance of 10 TΩ and low input bias current of 25 pA maximum. The converter is available in an 8-SOIC package and is suitable for surface mount applications.
This device is ideal for upgrading the performance of non-RMS precision rectifiers, offering higher accuracy at a comparable or lower cost. Its design ensures compatibility with high input impedance ADCs, minimizing DC offset errors at the output.
