The AD737KRZ from Analog Devices is a low power, precision, monolithic true RMS-to-DC converter. It is designed to compute the true RMS value of input voltages, making it suitable for a wide range of applications including battery-powered devices and multimeters.
This converter features a wide power supply range of ±2.5 V to ±16.5 V and a low standby current of 25 μA. It provides high accuracy with a maximum error of ±0.2 mV ± 0.3% of reading for sine wave inputs. The device can handle signal crest factors up to 5 and maintains accuracy for various input waveforms, including variable duty cycle pulses and phase-controlled sine waves.
The AD737KRZ has a high input impedance of 10^12 Ω and a low input bias current of 25 pA maximum. It is available in an 8-SOIC package and is designed for surface mount applications. Its low power consumption and precision make it an ideal choice for upgrading performance in applications previously using non-RMS precision rectifiers.
