ADE7754ARRL

Overview

The ADE7754ARRL is a polyphase energy metering integrated circuit manufactured by Analog Devices. It supports 3-phase/3-wire and 3-phase/4-wire configurations with less than 0.1% active power measurement error over a 1000:1 dynamic range. The device integrates second-order sigma-delta ADCs, reference circuitry, and a temperature sensor. It operates on a single 5 V supply within a -40°C to +85°C temperature range. Key electrical parameters include 7 mA supply current, 70 mW power consumption, and SPI interface compatibility.

Feature Summary

• Integrates second-order sigma-delta ADCs for high-accuracy signal processing
• Provides digital calibration for power, phase, and input offset
• Includes on-chip user-programmable thresholds for line voltage sag and overdrive detection
• Features a pulse output with programmable frequency

Applications

• 3-phase/3-wire energy metering systems
• 3-phase/4-wire energy metering systems
• IEC 687/61036 compatible utility meters

Procurement Notes

Verify the specific suffix ARRL against official Analog Devices documentation to confirm package type and reel specifications. Confirm availability status as distribution channels may indicate limited stock or obsolete status. Ensure environmental compliance data matches the required RoHS standards for the target application region before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high accuracy in polyphase energy measurement without external DSP requirements. The integrated temperature sensor and digital calibration features simplify system design. Ensure the host microcontroller supports the SPI interface and can handle the interrupt request line for efficient data polling and status monitoring.

Part Context

The ADE7754 belongs to the ADE7754 series of polyphase multifunction energy metering ICs. It is designed to replace discrete solutions by integrating ADCs, signal processing, and calibration logic. The part is distinct from single-phase variants like the ADE7753 and offers comprehensive waveform sampling capabilities for advanced metering infrastructure.
