ADE7755ARSZ

Overview

The ADE7755ARSZ is a polyphase energy metering integrated circuit manufactured by Analog Devices Inc. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and consumes 17.5mW typical power. The device features a 16-bit resolution and includes two ADCs within a three-channel architecture. Packaged in an SSOP-24 format, it supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates analog-to-digital conversion and reference voltage circuits for high stability in harsh environments
• Calculates instantaneous and average active power using direct multiplication methods
• Provides pulse outputs for driving electromechanical registers or microcontrollers
• Includes internal phase matching and empty load threshold detection to prevent creeping

Applications

• Single-phase smart electricity meters
• Industrial electricity meters with CAN bus interfaces
• Recurring tariff electricity meters
• Electric locomotive energy measurement systems

Procurement Notes

Verify the specific suffix ARSZ against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with EVAL-ADE7755ZEB evaluation boards if development support is required. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement plans.

Selection Notes

Select this component for applications requiring IEC 61036 standard compliance and high accuracy in single-phase metering. Consider the SSOP-24 package constraints for PCB layout. Evaluate the need for external gain calibration if utilizing low-resistance shunt resistors in the current channel design.

Part Context

The ADE7755 series represents a specialized line of data acquisition components designed for energy metering. It utilizes digital signal processing to maintain accuracy over time, distinguishing it from purely analog solutions. This part belongs to the broader ADE family, which supports various polyphase and single-phase configurations.
