AD736KR

Overview

The AD736KR is a monolithic precision true RMS-to-DC converter manufactured by Analog Devices Inc. It operates within a supply voltage range of -3.2 V to 16.5 V and features a maximum operating temperature of +70°C. The device utilizes silicon technology and is housed in an SOIC-8 surface-mount package with tube packaging. Key electrical specifications include a switching frequency of 33 kHz, a maximum duty cycle of 50%, and a quiescent supply current of 200 µA. It provides an output current capability of 2 mA and is designed for AC/DC conversion applications.

Feature Summary

• Performs direct true root-mean-square to DC conversion without relying on average value approximation methods.
• Integrates input amplification, full-wave rectification, and RMS core processing on a single silicon die.
• Supports flexible input configurations for both high-impedance and low-impedance signal sources.

Applications

• Precision measurement of non-sinusoidal AC voltage waveforms
• True RMS voltmeter circuit design
• Power monitoring systems requiring accurate AC/DC conversion

Procurement Notes

Verify the specific suffix 'KR' against official Analog Devices documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the required operating temperature range and interface requirements before procurement.

Selection Notes

Select this component when precise RMS measurement of complex waveforms is required. Consider the 200 µA power consumption and SOIC-8 package constraints. Verify that the -3.2 V to 16.5 V supply range aligns with the system design.

Part Context
