ADE7761BARS

Overview

The ADE7761BARS is a single-phase energy metering integrated circuit designed for 2-wire distribution systems. It operates on a single 5 V supply and features an SSOP-20 package. The device includes four analog-to-digital converters (ADCs) and supports a supply voltage range of 4.75 V to 5.25 V. It functions within a temperature range of -40°C to +85°C. The component provides high accuracy active energy measurement, supporting IEC 62053-21 standards with less than 0.1% error over a dynamic range of 500 to 1. It utilizes proprietary ADCs and digital signal processing for precision.

Feature Summary

• On-chip fault detection and missing neutral monitoring for 2-wire systems
• Direct drive capability for electromechanical counters and stepper motors via frequency outputs
• High accuracy active energy measurement using digital domain signal processing
• Continuous current monitoring to select the larger phase or neutral current for billing

Applications

• Single-phase electricity metering in residential or commercial utility applications
• Energy monitoring systems requiring fault detection in 2-wire distribution networks
• Integration with electromechanical or stepper motor-based mechanical counters

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as the provided model lacks the standard 'Z' lead-free designation often found in current production variants. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited supply or obsolescence. Ensure the procurement source provides valid traceability and authenticity guarantees for specialized data acquisition components.

Selection Notes

Select this component when designing single-phase energy meters that require integrated fault detection and direct drive for mechanical registers. It is suitable for applications needing high accuracy over wide dynamic ranges without external digital signal processing. Consider the SSOP-20 package constraints and the requirement for a stable 5 V power supply during system architecture planning.
