AD7751AN

Overview

The AD7751AN is a high-accuracy, fault-tolerant electrical energy measurement integrated circuit designed for use with two-wire distribution systems. It features on-chip power supply monitoring and creep protection. The device supports direct drive for electromechanical counters and stepper motors via frequency outputs. It operates on a single 5 V supply with typical power consumption of 15 mW. The component utilizes proprietary ADCs and DSP technology to maintain accuracy over environmental variations.

Feature Summary

• Supports average real power calculation on frequency outputs F1 and F2
• Enables continuous monitoring of phase and neutral current for fault detection
• Includes on-chip 2.5 V reference with external overdrive capability

Applications

• Two-wire distribution system energy metering
• Electromechanical counter direct drive
• Stepper motor control applications

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with existing board layouts and voltage requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for applications requiring compliance with IEC 687/1036 standards. It is suitable where low power consumption and single-supply operation are critical. Consider the SSOP-24 package constraints during PCB layout planning.

Part Context

This component belongs to the ADE7751 series of energy metering ICs from Analog Devices. It is engineered for residential and commercial electricity metering applications. The series emphasizes high accuracy and fault tolerance in single-phase environments.

Replacement Considerations

Check for ADE7751ARS or ADE7751ARSRL variants for different packaging options. Verify pinout compatibility if substituting with other members of the ADE7751 family.
