ADE7755AN

Overview

The ADE7755AN is a polyphase energy metering integrated circuit manufactured by Analog Devices Inc. It features a 16-bit resolution and supports three channels for comprehensive power measurement. The device operates on a single 5 V supply voltage and functions within an industrial temperature range of -40°C to +85°C. Packaged in a 24-lead SSOP, it integrates pulse outputs for direct energy registration.

Feature Summary

• Integrates analog-to-digital conversion with digital signal processing for active, reactive, and apparent energy calculation
• Provides calibrated pulse outputs proportional to measured energy quantities
• Includes internal calibration registers to compensate for gain and phase errors

Applications

• Polyphase electricity metering systems
• Three-phase energy monitoring equipment
• Industrial power management instrumentation

Procurement Notes

Verify the specific suffix against official documentation, as package variations exist. Confirm availability status through authorized distributors, as supply levels may fluctuate. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for applications requiring high-accuracy polyphase energy measurement without external microcontrollers for basic calculations. Consider the SSOP package constraints for board layout. Verify that the 5 V supply requirement aligns with the system power architecture before finalizing the design.

Part Context

This part belongs to the ADE7755 series of specialized data acquisition ADCs designed for energy metering. It represents a dedicated solution for utility-grade metering applications, distinguishing itself from general-purpose converters by integrating necessary metrology algorithms directly into the silicon.

Replacement Considerations

Consult official substitution lists for pin-compatible alternatives. Verify functional equivalence regarding energy calculation accuracy and interface compatibility before replacing.
