ADE7752BARWZ

Overview

The ADE7752BARWZ is a polyphase energy metering integrated circuit designed for high-accuracy applications. It supports 50 Hz and 60 Hz systems, complying with IEC62053-2x standards with less than 0.1% error over a dynamic range of 500 to 1. The device is compatible with 3-phase/3-wire delta and 3-phase/4-wire Wye configurations. It provides average real power on frequency outputs F1 and F2, while the CF logic output supplies instantaneous real power. The part operates on a single 5 V supply with typical low power consumption.

Feature Summary

• Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time
• On-chip power supply monitoring and creep protection (no load threshold)
• Logic output REVP indicates potential miswiring or negative power for each phase
• Direct drive capability for electromechanical counters and 2-phase stepper motors

Applications

• Polyphase energy metering
• Electromechanical counter driving
• Stepper motor interface

Procurement Notes

Verify the specific suffix BARWZ against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required voltage levels and configuration settings before integration. Cross-reference ordering information with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component for applications requiring high accuracy in polyphase energy measurement. Consider the single 5 V supply requirement and low power consumption characteristics. Evaluate the need for direct drive capabilities for electromechanical counters versus digital MCU interfacing based on system architecture.

Part Context

The ADE7752 series includes variants such as ADE7752 and ADE7752A, which share similar functionalities but may differ in power consumption specifications. The ADE7752A typically offers lower power consumption compared to the standard ADE7752. All variants utilize CMOS process technology and are designed to surpass IEC62053-2x accuracy requirements.

Replacement Considerations

Check official documentation for confirmed substitute part numbers within the ADE7752 family. Verify pin compatibility and electrical specifications before substitution.
