ADE7752BARWZ-RL

Overview

The ADE7752BARWZ-RL is a polyphase energy metering integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.75 V to 5.25 V and consumes typical power of 60 mW for the standard variant. The device supports 50 Hz and 60 Hz frequencies, maintaining an error of less than 0.1% over a dynamic range of 500 to 1. It is housed in a SOIC-24 package and functions within a temperature range of -40°C to +85°C. The component utilizes proprietary ADCs and DSP for high accuracy.

Feature Summary

• Provides average real power information on low-frequency outputs F1 and F2 for direct drive of electromechanical counters or MCU interfacing.
• Supplies instantaneous real power via a high-frequency calibration output (CF).
• Includes logic output REVP to indicate potential miswiring or negative power conditions per phase.
• Features on-chip creep protection with a no-load threshold and power supply monitoring.

Applications

• Three-phase three-wire delta configuration metering
• Three-phase four-wire Wye configuration metering
• Direct drive applications for electromechanical energy counters
• Control interfaces for two-phase stepper motors

Procurement Notes

Verify the specific suffix 'B' against official documentation to confirm if it denotes a distinct revision or variant compared to the standard ADE7752A. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the SOIC-24 footprint matches the PCB design. Validate that the 5V single-supply requirement aligns with the target system power architecture.

Selection Notes

Select this component for applications requiring high accuracy over large environmental variations due to digital signal processing. It is suitable where direct drive capabilities reduce external component count. Consider the 60 mW typical power consumption for thermal management. Verify compatibility with IEC62053-2x standards if regulatory compliance is required for the final product.

Part Context

This part belongs to the ADE7752 series of polyphase energy metering ICs. It integrates analog-to-digital conversion and digital signal processing to perform multiplication, filtering, and summation in the digital domain. This approach ensures superior stability and accuracy over time and extreme environmental conditions compared to purely analog solutions.

Replacement Considerations

The ADE7752A is functionally identical to the ADE7752 and may serve as a substitute. Verify pinout and electrical specifications match before replacing. No other direct public substitutes are confirmed in the provided data.
