ADE7751ARS

Overview

The ADE7751ARS is a high-accuracy, fault-tolerant electrical energy measurement IC designed for 2-wire distribution systems. It supports 50 Hz and 60 Hz frequencies with less than 0.1% error over a dynamic range of 500 to 1. The device operates on a single 5 V supply with typical power consumption of 15 mW. It features two frequency outputs (F1, F2) for average real power and a continuous monitoring function for phase and neutral currents. The package is SSOP-24.

Feature Summary

• Supports direct drive for electromechanical counters and 2-phase stepper motors via frequency outputs
• Includes on-chip creep protection and power supply monitoring
• Features programmable gain amplifier in the current channel for small shunt resistance use

Applications

• Energy metering in 2-wire distribution systems
• Calibration of electricity meters
• Monitoring phase and neutral current faults

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel configuration. Ensure compatibility with IEC 687/1036 standards if required for your application. Check for RoHS compliance status in the latest datasheet revision.

Selection Notes

Select this component for applications requiring high accuracy and fault detection in single-phase or split-phase systems. Consider the SSOP-24 package constraints and the need for external components if overdrive capability is required for the internal reference.

Part Context

Part of the ADE7751 series from Analog Devices, specialized for energy metering. It integrates proprietary ADCs and DSP technology to maintain accuracy across environmental variations. The device is designed to surpass standard accuracy requirements for utility metering applications.

Replacement Considerations

Check for ADE7751ARSRL as an alternative reel version. Verify pinout and functional equivalence before substituting with other energy metering ICs from different manufacturers.

FAQ

How does the ADE7751 handle fault conditions?

It continuously monitors phase and neutral currents, using the larger of the two for billing during faults, and provides logic outputs to indicate miswiring.

What is the typical power consumption?

The typical power consumption is 15 mW when operating on a single 5 V supply.
