MX636JCWE+

Overview

The MX636JCWE+ is a true RMS-to-DC converter manufactured by Analog Devices / Maxim Integrated. It computes the RMS value of AC and DC signals with a bandwidth of 1 MHz for input voltages greater than 100 mVrms. The device features an auxiliary dB output with a 50 dB range, operates from single or dual supplies, and draws a typical quiescent supply current of 800 µA. It accepts complex input waveforms containing AC and DC components.

Feature Summary

• Performs true RMS-to-DC conversion for signals containing AC and DC components
• Provides an auxiliary dB output for signal level indication
• Operates from either single or dual power supplies
• Features low power consumption suitable for battery-powered applications

Applications

• Digital multimeters
• Battery-powered instruments
• Panel meters
• Process control systems

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity and pin alignment against the SOIC-16 specification. Review the official datasheet for handling precautions and storage conditions. Ensure compatibility with existing circuit designs regarding supply voltage ranges and thermal requirements before procurement.

Selection Notes

Select this component when precise RMS measurement of complex waveforms is required in low-power environments. It is suitable for applications needing a wide dynamic range and high accuracy without external trimming. Consider the 1 MHz bandwidth limitation for high-frequency signal processing needs compared to higher-speed alternatives.

Part Context

This part belongs to the MX636 series of true RMS-to-DC converters. It shares functional similarities with the MX536A but offers specific performance characteristics tailored for lower input voltage ranges starting from 0 to 200 mVrms. The series is designed for laser-trimmed accuracy, eliminating the need for external adjustments.
