AD736KRZ

Overview

The AD736KRZ is a low-power, precision monolithic true RMS-to-DC converter manufactured by Analog Devices Inc. It features laser trimming for high accuracy with a maximum error of ±0.3% on sine wave inputs. The device operates from a wide power supply range of +2.8V to -3.2V up to ±16.5V and consumes a maximum supply current of 200µA. It provides a buffered voltage output with a specified precision that requires no external trimming. The component is housed in an 8-pin SOIC package and is designed for applications requiring precise measurement of AC and DC input voltages.

Feature Summary

• Laser-trimmed precision architecture ensuring high accuracy across diverse input waveforms
